LIVE!!! Calling all XM chip, 3930K/3960X and ultrabook owners! Heat-Spring TIMs for testing!

Well unless you have access to intel's XTU, then you can edit turbo times, TDP limits etc. But only a few machines do.

 

Started to log CPU & GPU temps, CPU usage, CPU and GPU clock's, CPU wattage and Fan's speeds. Will be about 5-10 hours of logs per day.
I'm usung Alienware M15x with OEM Core I7 920XM on 4-5 month old CoolLaboratory Liquid Pro.
For day-to-day use i have 25/24/17/17 with 57W/47A TDP/TDC, for render i'm using 26/26/20/20 with 70W/60A and for benchmarks 27/26/25/25 with 87W/72A.

In plans to log 1-2 weeks with almoust 5 mounth old CL Liquid Pro, and repast to Arctic MX-4 for 1-2 weeks. In total if you will decide to send Indium - will apply and test Indium, if not than will apply fresh CL Liquid Pro.

 

Alright, PM sent.

HF, I've been using ThrottleStop to keep my processor from reaching 90+C whenever I game. I can turn it off for the monitor but only maybe 15 minutes at a time. Too afraid because my processor reached 100+C once when I played Alan Wake.

EDIT:

Posting this as per requirement.

HP Pavilion dv6-7009tx / Intel Core i7-3610QM / 16GB RAM / NVIDIA GeForce GT 650M

Temps

CPU: Around 45-52C idle when in 28-30C ambient temp room; About 85C for Mildly intensive games, but reaches cap (which I set thru ThrottleStop) when I play more recent games--gets as hot as 92C (Turbo off). I can probably push it to more than 100C because I remember getting to 101C before I turned off Turbo whenever I game.
GPU: Around 77-80C for non-intensive games, reaches 85C for more intensive ones. Idles around 36-39C.

TIM
IC Diamond 7

I'm willing to shoulder shipping costs and do the monitoring you need.

I agree to all terms and conditions and will comply with the needed tasks and provide my data for the Heat Spring TIM testing.

 

One more thing HF, I noticed you have the die size incorrect for the 920XM; it is actually 14mmx25mm (about 9/16"x1"), I just measured it with a dial caliper.

 

i measured my 720qm should be the same chip

I used a plastic ruler though. I'll double check tomorrow...hands covered in grease and crap from my truck so don't want to touch my old CPU

 

=) I was a machinist for 20 years before my back crapped out, I will personally guarantee these measurements to be accurate within .005". But if you think you can get closer with a ruler...lol. :thumbsup: The actual inch dimensions would be ~.540"x.984", whereas 9/16"x1" is .5625"x1.000". Basically the difference between the inch sizes and the metric would be the thickness of 2-3 sheets of paper.

Edit to add: Not sure if there might be some variation between dies...I don't know how picky they are with cutting them to size from the wafer, it's conceivable that they cut them slightly larger than they have to be to ensure the circuits are not so near the cut edge as to be damaged during the cutting process.

 

I'm fairly certain that all of the die's are 'exactly' the same size

 

Hey HF. Do we start logging and sending data before you choose, or do we wait for you to tell us to start?

 

I have done my 5 minute idle log and will probably do my 1 hour burn test tomorrow. I am still waiting to hear what exactly he wants for the week-long log...if that's just supposed to be logging while doing general tasks and just start and stop the logs every time we start or shut down the computer, or??? I tried PM'ing him about it but got no answer. I thought maybe he didn't answer because he was doing the template he was talking about.

 

started on template and super behind in real life stuff. got class to day and tons of homework. and had to work on VA stuff and got to talk to lawyer and probably starting new job Wednesday while going to school full time. just get your logs done. Sorry for beiong so far behind. I thought I had more time. I'll probably work on it friday and have it done friday since i got no class or homework due but until thursday i am toast. I hope i get it all done lol. the week long test just record it for a week of all your general use. I would like if you could get as much F@H time in if possible but if not no worries. I'll post later tonight whos info i got and if your not on that list yet get to me. If you already got to me about it get with me again might have forgotten. I'll start mailing next Monday I think

 

hey i'll finish template tomorrow i think. Working out details of contract for job still so i wont start until Monday the earliest so check back thursday and everything should be a go.

 

hey whats the difference between CPU package temp and core max temp? how are they affected? I get core max but whats core package?

nm core package temp is max temp of total CPU whether it is CPU core, GT core, or IA core.

UPDATE: Have a 80% complete power point.

I would like everyone to do testing to have a 5 min idle test and 15 min burn test and just post files here and I'll make the charts. Took me about 10 mins to figure it out and get it all to work. Only take 5 or so mins to edit 4 excel logs. If you want to be awesome and make the whole Powerpoint file like I did that would be awesome otherwise do everything I have done in the powerpoint and post the files for myself and others to finish for you.

I will add a few more things to the powerpoint file later like a comparison chart of temps along with the individual charts. I also need to do the pressure paper since I did not have it on hand at the time. Jim sent me some so I'll include that too when I send everything out. Took me about 30-45 mins to figure out what I wanted while watching a movie but will take like 20 mins now since I know what I want. Does anyone have any questions? Am I missing anything?

Also as stated in the PowerPoint Heat-Spring in it was a total bust because of the cheap flimsy heat sink. I'll elaborate more on that later. When I post the detailed pics of the heatsink and how junky it is I want to make sure no one else has a heat sink like that because it'll just be a waste of time. Now we know of a good example of where Heat-Spring is even worse off so lets see how it works in a real heat sink

http://www.filedropper.com/heat-springpowerpointtest

 

Alright, I guess I'll start. But just a heads-up, HF, I kinda had this epiphany and realized that the fan in my heatsink is closed off on one side--that's the reason why I reach such high temps. Now I just top at about 92C even with TurboBoost, and I think this is now because of the heatsink itself. Am I still qualified?

 

Hmmm... depending on the actual dependancies - wouldn't that make you More qualified?

 

I just purchased a Samsung Gamer with i7-3820 and GTX 675m and waiting for it to arrive. Not too sure how easy it is to pull appart but it will get ICD and then if this stuff becomes available later I'll try it as well. The heat transfer capability sounds awesome to say the least. While it sounds expensive something that works this well and will last a long time is hard to resist.

 

You can do what I did and drill out the bad plate. my temp dropped like 20+ C when I did that.

I am only doing the couple desktops already picked. desktops require a lot of material.

 

It is a laptop i7-3820qm and GTX 675m, however I am not looking to become a tester. I am looking to hopefully later purchase it outright. I will though share my results, good or bad.

 

It's not really as much a plate as it is a plastic fan cover on the fan itself. I did already. Before I took it out I reach 90C above when I play demanding games like Sleeping Dogs, without Turbo. Now I only get to reach it with Turbo on. Lols I think that's an improvement in itself )))

 

so your fan is no longer covered?

EDIT: yea the pressure paper didn't even show anything for the netbook lol. Though this pressure paper is different. It doesn't change colors but more so changes transparency I guess. I might buy the fujitsu paper anyways since that changes color and shows up better.

 

Yeah not anymore. It does still reach 90+, just when I turn on TurboBoost.

 

OK, here are my 2 Excel spreadsheets from Idle and Burn logs:

...This is a heatsink issue, unfortunately its very difficult to MOD a heatsink, but that is what needs to be done, and i dont mean add a few heatram sinks to it or cut a hole in the cover and place a few fans under it, i mean re-engineer the pipes to allow a greater flow capacity for heat transfer. I stated this before but i feel that the top CPU pastes have pushed the capabilites of all the current heatsinks to their heat transferring limits.

 

everything works in unison. so yes heat sink is not good enough but paste does help. I am feeling rather lazy right now and don't want to elaborate but my cooling thread shows about everything that is possible to do...minus watercooling...that is currently on the back burned because this project is more pertinent.

 

Yes and no to the heatsink mod. Every system is different but the norm is a heatsink is more capable with proper heat transfer. Here is generally what happens

At the first start of a load the chip starts to heat up. If the transfer is good the heat moves quickly to the heatsink cooling the chip itself. This then heats the fluid in the pipe faster for it to dissipate out to the fins faster. Getting the liquid to cool faster and return to the heat collection pad sooner.

With bad transfer the chip heats up and slowly heats up the heat pipe. Once this gets to proper temps it starts sending the fluid in the pipe to the dissipation fins through evaporation. In the mean time the chip is just heating up even more from the slow heat transfer rate. By the time the cooled liquid returns the chip it is already approaching overheating causing what appears to be early over saturation of the cooling system.

Now a cooling system can still be over saturated, there is no arguing that. Without the fastest possible heat transfer though it will over saturate faster and more easilly. With super fast transfer of heat, especially under normal use, in borderline cases you may even prevent heat over saturation alltogether...................

Edit; please don't shoot me, this is an overly simplistic explination............

 

btw i heard its a gas

 

Actually it's both usually for most laptops. There is usually some liquid and some vapor in the heat pipes. They cool using the phase change...going from one form to the other. TANWare explained it pretty well, if a bit simplistically.

 

Really? Non-solid elements in laptop heatpipes?

I don't know who to ask, but do you guys know how to measure for clearances inside laptops? I bought a set of RAM heatsinks (those Cosmos ones) and I want to put them in my heatsink. I can take pictures. )

 

Yes, by definition a heat pipe contains liquid and some form of wick. The wick can be a literal wick such as desoldering braid, or it can be a high-surface-area sponge-like formation of copper completely covering the entire inside diameter of the tube. The system works by absorbing heat from the CPU, which heats any liquid present at the chip end of the heat pipe, this in turn flows to the cooler end of the heat pipe through convection, then cools at the radiator/heat sink and re-condenses to liquid. The wick brings it back to the hot end of the heat pipe through capillary action to begin the process anew. The fluid is normally water, and it is able to be vaporized at lower temperatures because the heat pipe is under vacuum, which allows the water to boil at much lower temperatures.

A very simple, safe way to measure for clearance in tight spots of any variety is to use modeling clay or Play-Doh. Put a blob in there, assemble everything, take it apart, and then cut the clay to see the cross-section and check thickness, which will of course equal your clearance.

 

Good attempt, but the heatpipes in "notebooks" carry no true liquid or special gas based substances, Wikipedia or whatever source you pasted from is correct with conventional/common (however you want to state it) heatpipes, but our laptops do not use conventional heat pipes.

Basically the idea of our laptop heatsink is that convective heat transfer is proportional to surface area. Larger surface area (ie: lots of fins/pipes) = lots of thermal 'flow'. Our cheap laptop heatsinks are vacuum sealed to remove air (air=heat) from the hollow pipes, crimped just above the vacuum as to not allow air back in, simple but effective.

Desktop CPU heatsinks/pipes, have the technology in which you mentioned so i will not try and restate that, also the desktop has the size and capabilites to create a true heat tranfering system with all those elements.

 

Ok, show me where you get this info? I can tell you my P79 on the CPU/GPU does just by its behaviour but I'll bite.............

 

Yes they do use "conventional" heat pipes. A friend of mine owns a computer repair business, and I have personally cut old heat pipes from laptops open and seen the wick surface inside. You are incorrect Mike. Most common laptop heatpipes use common deionized water as their "fluid." And there isn't much in there, so don't expect to cut one open and be greeted by a fountain.

 

Times change as well as heatsinks, incorrect no, as there are different types of heat transferring sinks. And the most conventional in todays laptops can very well be the convection based pipes with the wick. This is still a heatsink issue more than a thermal conductivity problem IMHO.

 

You are right. My P6860FX heatpipe contains some small amount of white transparent liquid.

 

You mean the shop didn't flood out................

Yes there is some point of diminishing returns and eventually no matter how good the thermal conductivity any heat exchanger can flood out. The idea is not to take the heat exchanging system out prematurely with poor thermal conductivity................

 

BTW putting in order tonight for pressure paper since the stuff Jim sent me is not very accurate. It just turns transparent under pressure so i have no idea what the measurements would be...can only tell if you have even contact as far as I know.

 

I have a 2960xm in my current MSI that easily reaches 90degrees while gaming. Haven't read through the entire thread, but if there is anything I can help with, let me know.

 

Sorry for being slow I got exams all this week. I also got some more pressure paper in and trying to figure out where i can get it analyzed (I guess it just changes transparency...i thought it changed colors :/ so i have to figure that out before i can send you guy's samples). Also for testing we will use intel burn test.....holy crap that eats your CPU up. F@H gets me 55-60ws and intel burn test gets me to 60-67watts and added 10-15C So who ever sent me their testing already redo load test with intel burn test...keep an I on temps it eats it apart. Makes prime95 and F@H look like a chump

 

quote from TI forum to update you guys.

 

Hey dude,

Yup I can do some testing as well. It would be interesting to see how it holds up during long intense 100% load whilst F@H is running.

Cheers.

 

cool cool. Get your stock testing done and i will mail as soon as we work out money for shipping. I'll post later tonight what I need. Off to fix truck Than class hurray!

 

updated with minor change. I want people to also do Intel Burn test if they have room with temps. Don't run it if you will hit TJMax. I am starting to send samples to several people this week so please get your stuff in!

 

woot PCsensor finally got back to me on where I can get drivers for my TEMPer B and now I am logging ambient temps! This weekend I'll start doing my tests!

Everyone that has gotten back to me I'll get back to you tomorrow on what I need from you or if i am sending you samples.

Also do any of you guys have questions or comments....have I forgot anyone? Sorry for being so busy lately.

EDIT: I updated the info of who has given me addresses/log info and who hasn't.

 

sent 3 samples to reborn!!! Have I missed anyone?

EDIT AFK until Sunday due to homework and exam. PM/email me logs and i'll save them and look at them over the weekend. I'll start sending more samples next Monday to whoever has finished.

 

Got caught up with work and now I've gotten left out of the loop. Anyway, I don't think I'd still have time to do precise logs so I won't be pestering anymore, HF. Sorry. I'm also pretty sure it'll be hard with me not being in the US.

Still subscribed to the thread though. Would want to see the results someday.

 

ok sorry to hear

 

hey guys sent off samples to reborn and APU71 and still need more guys to test this. I got 6-7 2x2 pieces left. I'll be using 1 for myself to test out in the near future. Nearly built my custom cooling pad and changed my design for it lol so i got to start over. I am on 3rd design now and it is definitely going to be the best one and work great. Probably make the new design this week. It'll take maybe an hour or two to make....so much better and faster than the other designs hahah. Could have made it ages ago :/ At least this one will be well made! I can say i am no small project designer yet lol. Just learning about all these different materials that excist. Home depot doesn't carry a lot as i am learning hahaha. I'll also post the pressure paper articles in a few hours. Wife is sleeping and can't get to them without waking her. I don't need a fire breathing morning breath dragon trying to kill me because i woke it up ^-^


EDIT: I changed some of the terms to be lower requirements. I also cleaned up and clarified some parts.

EDIT: Again as always...i am not missing anything or anyone right? I am inherently forgetful so please keep PMing me because i can be dumb somethings ^-^

Also APU71 I want to formally apologize to you. Sorry for taking forever! I got distracted with a bunch of other side projects along with being busy and lazy. You will get it probably Tuesday or Wednesday. I sent it 2-3 days as of Friday VIA USPS. The tracking number is in your PM box.

Cheers I hope it works well for you! Remember to follow directions and tighten the hell out of it....just don't crack die I do hope you don't take as long as I did to mail it to you but I can't really say anything can I

Also I'll post my video of heat-spring and pictures of application today or tomorrow depending on a couple of things. (largely I need to find where I put those files -_-) Also need to video edit the video.....It took like 10 tries for me to get it right lol but one part was wrong so got to cut it out

 

Looking forward to these results, can't wait!

I know how hard it is to take on side projects like this (time-wise) when the rest of our demanding life is demanding our full attention. I know it will be worth it in the end; hang in there and you'll feel great when these results are in.

I know I am already appreciating the work and effort you're putting into this (along with all the effort of the participants too, of course).

When do you think some results will be posted? (Yeah, I'm too eager...).

 

only two people have stuff Reborn and APU71 (his is in mail) no one else has gotten back to me with pre requirements yet. I'll do my testing in my R4 this coming week and I'll test my G51j with the 920xm when i get my cooler built. Taking me forever to finish that keep cahnging designs because they don't work out well. This new design will be perfect and take me maybe 2 hours to build

 

You don't have to apologize! Life is busy! I understand that. I'm very excited to get the Tim and start testing it out!
