The P-7811 cooling and temperatures thread.

Now I know there are a lot of threads out there at the moment where one could extract this sort of information. “My P-7811 is overheating!” etc…but I figured it would be nice to have a consolidated thread dedicated to our notebook temps and cooling etc.

CPU IDLE 40-43, Mild usage 45-46, Stressed to the absolute maximum: 56-57. (100% CPU usage for about an hour or more achieves 57 degrees
GPU Idle 37-40, Mild usage 52-56, Gaming 58-60, stressful gaming 70+ I need to do my gaming tests again if I can find the time, but it never reached 80.

HD The average is 51 though if the laptop has been on for a long time or the disk is being written to a lot it gets to 60.

No undervolting has been done and neither has any hardware modifications (Thermal pastes etc). I am running a clean install of Vista 64bit with the stock drivers I made with the gateway recovery thingy. All with the exception of my video drivers in which I am using the latest from laptopvideo2go or whatever that site was called.

Environment is South Florida with an air conditioner that does not work as well as it should. These temps have been gauged with the laptop laying flat on a wood desk, with the exception of my gaming temps. I propped up the lappy for those.

Based on what I have read, my idle CPU temps seem to be a bit higher than some. Though don’t get me wrong, I am aware my temps are completely normal and stable. My GPU seems to be pretty standard, though my gaming temperatures have not been monitored as good as they should have been. I need to work on getting something to display my temps as I game. And as far as the HD goes we all know the story with the HDs in the P-7811.

My experience with the NZXT CYRO notebook cooler: Using the Notebook’s power it did not seem to make a big impact on temperatures. It did not seem to help my CPU temperatures at all and seemed to have minimal affect on the GPU. However the HD temp would max out at 51 instead of 60 which is a plus. I will be updating this information as I test this thing more thoroughly, I can’t seem to find much time lately. I suspect the locations of the P-7811’s vents are what keep the Cyro from cooling at its maximum potential.

My main goal for this thread is to have something where us people who seem obsessed with temperatures can compare notes and get our notebooks running at optimized temperatures, Whether it’s for over clocking or just to keep cool.

A few questions I have are what sort of temperatures am I looking for in order to over clock this thing? What is the maximum I should take my chances with and what did you all do (If anything) to achieve your current temps?

 

Sitting my P-7811FX on a flat top desk.. Running Call of Duty 4 at 1920x1200 (Or whatever the Max resolution is..).. my GPU reached 81c after 30 minutes of a gaming session.

I live in Georgia, it was about 12am at night.. but my house is normally warm.. Not hot but not cold.

EDIT: That's with everything stock.. No OC'ing done and using Xfastest's driver.

 

81c is just fine. Those cards do fine until 90c

 

Sitting Idle my 7811fx temps using HWmonitor:

Cpu Core 1 = 19C
Cpu Core 2 = 19C

Gpu = 38C

HDD= 29C

Note sure how hot my GPU has gotten while gaming have not checked yet, Although I have run Orthos stress test for over an hour and max CPU temps was 39C. Well thats at least what HWmonitor says. For my Idle temps I had my NC2000 cooler running. For the stress test I turned it off.

 

Are those temps completely stock? Stress testing my CPU for an hour gets me to 57...which is a pretty big difference in comparison. Hmmm

 

Sorry for the noob question. But it's "fine" to run at that temp for long periods of time, or would you want to give it a break from time to time? Gotta love the MMO timesinks . I'de probably turn it off over night to avoid killing something like I did in my desktop which I never turn off, been on for a few years straight aside from restarting and whenever the power goes off... 7 years later it's still working, but not as good as it used to lol

 

Remember that computers are made of lots of small metal pieces. So, assuming your not melting anything.. IE with really high temperatures, its better to leave them on.

Think what happens to metal when it gets heated and cooled repeatedly. It'ls really less stressful on the components not to be shutoff 20 times a day. By shutoff I mean allowed to cool and then reheated.

If your really concerned about long gaming periods on MMO's, get a NZXT notebook cooler. Works amazing for this laptop, even if the vents don't line up exactly right.

Me and the wife both play MMO's pretty hardcore, and she uses the desktop and I get the laptop with a NZXT notebook cooler, MX518 mouse, and a N52 gamepad. Works out pretty good and tempature is never an issue though I do keep an eye on it with HWmonitor 1.11

 

Because the CPU heatsink is so easily accessed, I highly recommend removing the stock thermal paste and replacing it with some good stuff such as AS5 or Ceramique...

 

My GPU was hitting about 85c when it was on a flat surface, when running wow. Then, I used a book in the back to raise the notebook without blocking any vents and the GPU stay around 65c. My cpu always stays about 50C in wow. and 32C idle. I hope that helps.

 

My laptop is going not higher than 62C on top of a Shoe Box in Vertical Possition, so all vents have like 3 inches to release air, this is when I'm playing Gears with all in MAX except the resolution to keep the framerate constant.

 

I have a solution for 6860 series and the CPU overheating. I placed a small piece of aluminum foil between the northbridge and the heat sink, and I can run my CPU at 3.0 maxing out at about 85C now, which is worlds better then before. If you do this make sure it doesnt touch anything else except for both heatsinks, as it wil short out your system. Mine shorted, but nothing was wrecked, thank god.

 

GPU maxed at 83 when lying flat on a cheap wood desk and playing Mass Effect.

Elevated the back with the FX's instruction manual and GPU temps dropped to the 70s.

 

When you say amazing...do you only see the difference when the laptop is under strain? Is there a difference in minimum temps? I am asking this because after running the day with my lappy flat on a desk....and then doing the same stuff on my NZXT at home....I see no difference. I plan to test myself but ive not found the time lately.

 

I see a significant difference... I couldn't tell you the exact variance. Some of it could be attributed to angle it's being kept at and some to the fans. I see a small difference in reduced min temps as well as a more significant reduced max temps. And a huge difference in peace of mind .

Also, I can take the cooler+laptop and fold the front part underneath and use it on my lap without blocking any of the vents and cooking the laptop. The front fold back part makes it so you can use the laptop on a bed or where ever you want because it protects the airflow space underneath.

Anyway, for $69 it's huge peace of mind and always propping the lappy up on a book or CD cases seemed kinda ghetto.

Overall, I wouldn't want to own a gaming laptop without it.

 

Try finding a dc to usb power adapter, plug a usb hub into the power adapter, and then plug both of the included usb cables (if you dont need the usb hub feature of the NZXT) into the usb hub. i guarantee it will work better than just plugging the cooler into the laptop. i know because i have the cooler plugged in exactly as described. ill wrangle up some pics if you need me to.

granted i have a 6860, but under load my cpu temp has only reached 50C one time, and 68C for the gpu. at idle i see low to mid 20's for the cpu, and 41C for the gpu, which is a lot better than what i was seeing before without the cooler.

 

Idk, mine spins just fine plugged into the laptop. BUT.. you have to plug it in right. I'm sure you checked this.. but if you plug both connectors into the left side USBx2 socket you won't generate enough power to actually turn the fans.

You have to plug the power connector into the right side USB port and the USBtoUSB connector into one of the left side sockets for it to work correctly.

Also, watch how you set the lappy on the stand. Don't put it so far forward that the HD vent gets blocked by that front side rubber pad. Back it off just a bit and all is well, but yeah your right it's not extremely effective at cooling the HD, but still helps.

Either way just flip it over and try different plugs till the fans actually spin.

If you already tried this do what the last poster said. If neither of those work idk what to tell you.. is your desk at work a notebook cooler in disguise?

 

Well I stressed my CPU out again and it maxed out at 50-51 rather than 57. I say thats a pretty noticeable difference.

One thing I find kinda odd though is the fact that when I was gaming yesterday, the left palm rest + keyboard got pretty darn hot even though the GPU was running at a very safe temp. Maybe the NZXT is blowing hot air up into the keys?

Anyway... 6-7 difference on stressed CPU temps is good enough for me to feel confident in my purchase. Now I gotta test what it does to the GPU. I guess you only see the benefits under stressed conditions...interesting.

 

Your right palm rest and the vent directly beneath it, I'm pretty sure is where the HDD is sitting.

Also, my ACPI on HWMonitor.. the top one.. hit 98C while playing Mass Effect.

Anyone know safe temp ranges for the ACPI nodes? Seemed a bit out of whack to me.

 

Wups... I meant left. Yeah I am aware of the HD heating up the right side. The Left got annoying though because my hand is resting there when I game.

I think I am going to undervolt and see how that goes. Not sure where to start...but that is what google is for.

 

my HDD was at 29C today, lol thats very cool. my GPU maxed at 76 when OCed while running 3dMark, and the CPU maxed at 75C @3.0

 

I assume 7200 rpm drives naturally run a bit more hot.

 

Managed to undervolt to 1.03v and shaved off a good 5c off of its stressed temps. That is with using a cooler so I need to see what I get without. But when using a cooler...the CPU doesn't seem to go over 55c. Not sure what the potential of the stock CPU is...but that sounds pretty good to me. Has anyone managed to get lower without any hardware modifications?

I remember someone on here claiming to be able to undervolt it to .9...but I am going to call bs on that one.

 

Hello all, just got my 7811 and love it! I've been trolling around for awhile and you guys really helped make my mind up and buy one. So, anyway I've been using it kinda "Jury-Rigged" using a mesh letter tray inbox type thing that I had from Walmart to sit it on for maximum venting. Seems to run pretty cool but looks, well not up to par. My question is two fold, do you think the NZXT is the best for this lappy or is the Zalman or perhaps this new Antec I found on NewEgg http://www.newegg.com/Product/Product.aspx?Item=N82E16834997410. If someone could yet again help me make up my mind I would appreciate it.

Access to the keyboard is not important to me for my desk, I use a USB KB with it and only use the KB on the laptop when traveling.

 

IIRC, if your ACPI is reading that high of temps, you have a defective sensor or something.

My ACPI temps are normally within 10C of my CPU temps. So far, with my laptop running F@H SMP, it hasn't gone over 55C and that's with it sitting flat on a wooden desk. My room temp is 25.5C. The GPU is another story. If I elevate the back of the laptop by about an inch, temps don't go pass 70C. If I don't raise it, temps get near 85C.

 

I changed from HWMonitor 1.10 to 1.11. With how fast the temp is changing I really think its a bug in the code when you alt-tab.

 

Just found an issue with the NZXT (at least I think its the device and not my machine) if I leave the hub plugged in while I boot, sometimes the computer refuses to boot. Sometimes if I plug it in during the boot...I get a BSOD.

One thing I noticed about the P-7811 FX is that it reinstalls the drivers to my USB connections every time I connect the device after a boot. Is this normal for vista or what?

 

no bs, reality. i undervolted p8400 to 0.925 and p9500 to 0.975. the stock voltage on this cpu is 1.3v. you are missing something. did you change your cpu type to mobile at rmclock?

 

Yes I did. I followed the instructions on a guide found on these forums to the T. I just double checked to make sure, however I still may be missing something. Hmmm

Oh....and I just noticed a typo of mine. I have mine running at 1.03v atm now 1.3, sorry.

So are you saying next to FID 8x you managed to bring it to .925? That should be the highest multiplier I should see in RMclock correct?

 

with the p8400, I got as low as 0.900. Orthos was giving errors when I dropped it to 9.125 so I settled with the 0.925 and ran orthos for an hour. I got no errors no bsd. Now every computer even the same model may have different setup duo the thermal paste and thickness of the sylicons etc but you should be able to down to 0.975 without a problem since I got the P9500 work at that voltage.

 

Maybe the BSOD I got at 1.02 was a fluke, leme try.

 

Nope...just tried...I cant undervolt any lower without getting a BSOD. If I dare take it to .9 or below...then I get an instant BSOD, I dont even need to have Orthos running. What could be causing such a drastic difference? Has any other 7811 owners managed to undervolt so low?

 

every cpu has its own uv threshold, other wise they would make a table telling you how much you should uv, however they state each multiplier should be tested thoroughly.

just as same cpus can give different temps, thats how it is, its normal.

 

I figured as much. One thing I have noticed...is some people can UV more than others...and some seem to have cooler temps...even with less uv...so its interesting how different machines differ.

 

its the cpu manufacturing process, no two cpu are exactly same.
you can read more here

 

Himm, it is a huge difference tough. Your voltages are too high for mobile processors, especially for the montevia cpus. I even got the T7500 on my wifes computer down to 0.9875. And I test it with orthos at least 45 minutes. I don't understand why you can not go more than 1.03.

 

Well orthos cant seem to get my CPU temp higher than 55c...so things seem to be in working order. Perhaps I have something configured incorrectly in Rmclock that is screwing the numbers I am seeing? I duno...RMclock is a very straight forward program and the guide was very concise, no idea what it could be. This is assuming that the voltage is as abnormal as you think.

 

Do you have 1.125 or 1.0 V right now?

 

Everest displays 1.14 under stress....which is different from what rmclock says...which is kinda weird. I just dont fully understand the process yet I assume.

Wups...my bad, for some reason performance on deman doesnt stay on when rmclock is restarted, so it wasnt undervolted. It is actually 1.05 at the moment.

 

Why are you using everest? Use CPU-z to check the CPU voltage. Use HWMonitor for the temps. That is all I use.

 

Because everest has been on par with every other tool ive used. It is just as accurate as hwmonitor from what I have seen. (I use both). I only use everest for the vista sidebar widget. Pretty neat program too.

 

my HD is at 57C :/

 

Yeah...thats quite "normal". If the NZXT cryo helped with anything...it was the hd...which never went past 50 with the cooler on. What worries me the most is when a second HD comes into play, guess we will see.

 

so should i buy a cryo, right now i have the laptop on my lap, but im using the cardboard box that the install cd's and stuff came in so my lap doesnt get hot

 

since we are all worried about temps here. check out the guide I made in my sig. It will make your life easy to watch temps at any time. whether gaming or desktop.

 

Did you ever figure out if that temp monitor sidebar stuff worked with the free Everest?

And has anyone else undervolted yet? I had a weird problem. RMclock will only go down to .9v and my highest multiplier was rock solid at that voltage. So I have no power on demand stepping.. it's all at .9v because thats as low as it can go.

 

Out of curiosity, do you have anything in your USB ports? Anything taking power from the laptop? I bet you thats why I cant undervolt so low.

 

NXZT notebook cooler and a Logitech MX518 optical mouse.

And undervolting dropped my 3DMark06 450 points and didn't help my temps all that much. I'm seriously considering scrapping it.

 

already did

 

not sure if you can do it in the free version or not. give it a go and let me know?

 

Useful guide...just recently got my notebook setup with it.

Still trying to figure out why people plugging in the same stuff as me can uv much much MUCH lower... *scratches head* I understand results may vary...but dang. luckily though...I seem to have a very cool running CPU..uv'd or not.
