Knock 5 degrees off CPU temps!

Got BF3 yesterday, and well, have become a bit of a no-life. I have Coretemp running and to shut down once CPU temp reaches 95 degrees. Happened 3 times between yesterday and today. For the most part, the max CPU temp was about 93 degrees, barely not shutting down. So I made a little stand out of Lego's to increase fresh air intake from the fans on the bottom. After a couple hours, made the maximum temperature 88 degrees, so a good 5 degree difference! Here's a picture of it.

 

nice. i stick a calculater toward the back on mine.played nfshp today and realtemp logging every 2 seconds showed 93 degrees after an hour or so overclocked with hyper threading on. raises the back bout an inch. wonder if it need raised a little more.

 

If you turn the Turbo Boost off, it would help reduce another 10C-15C, as for me, I have a cooler, I did have a test for it.

The test result below is base on Battlefield 3 gameplay:

With cooler (Turbo Boost On) I got between 87C ~ 95C Campaign and multiplayer is just about the same.
Without cooler (Turbo Boost On) I got between 90C ~ 99C Campaign only (I test this one at school, and the school block Origin), sometime it just crash/BSOD in the middle.

With cooler (Turbo Boost Off) I got between 66C ~ 85C in campaign (65C ~ 79C in Multiplayer)
Without cooler (Turbo Boost Off) I got between 78C ~ 95C in campaign (80C ~ 93C in Multiplayer)

So it's clearly show that the turbo boost is helping to increase the heat, Oh and for the performance, I didnt notice any different however I did notice sometime just before I got a crash/BSOD, I notice it start to stuttering and frequent lag spike, I think it is because of the high increase in heat. And btw I use Open Hardware Monitor to monitor the heat. The cooler I use is CoolerMaster Notepad U2.

 

Nice, I built one similarly, and noticed a difference. I'll maybe post pics later if you want them.

 

Yea, it's probably less ghetto than mine, I wanna see how you did it.

 

im thinking bout ordering the coolermaster notepad u2 cooler myself. What kind of fps difference did you see with turbo on or off?

 

Is 95 degrees going to kill the m14x or something? What about 99?

I have the Coolermaster Notepal U2 and I do not even use the fans it came with -- the metal stand is cool enough and allows for maximum air intake so I think it is basically all I need. It looks like it will not be comfortable in your lap but it actually is ok.

 

i wouldn't think 99 degrees is gonna kill a laptop right off but it is too high for me to feel comfortable with it. if it reaches 99 how much more will it take for it to go over 100? going over 100 could definately damage the system and i sure don't want to risk that.

 

95c? 100c is the default shutdown for your core i7 CPU. So its getting close. That is way too hot for my liking.

I recommend to everyone who gets an alienware to repaste the CPU and GPu with a quality thermal paste before you do anything. The stock paste they use is very mediocre...but the factory paste jobs that i have seen are HORRIBLE. no wonder so many CPU's are getting those high temps

I repasted both my CPU and GPU with prolimatech PK-1...apparently the best thermal paste on the market right now

After 5 mins of furmark extreme burnin...my 6990m is hovering at 67-68c
After 17 mins of prime95, my i7 2820 is sitting at 73c 71c 71c 72c

 

As I stated in my last post, I didnt see any performance difference though. But instead if I use it without a cooler, it seem to dip down quite a lot I think it is maybe because of the heat.

99C wont kill it, and I have experienced that, that's before I decide to get the cooler, the temp was record with HWMonitor reach 99C on Core 0 & 1 and the package (dont ask me about this cos I dunno what it is) reaches 100C!!! But it doesnt auto shutdown though, the game I played was BFBC2. See This for the pictures.

 

This proves once and for all that, aside from duct tape, Lego's are the most useful DIY tool ever! xD!

Gratz for such a clever idea!

I'm anxious to check the temps of my M14x after it is finally delivered sometime today...I'm willing to re-paste the innards, but seeing as I don't have any actual thermal paste on hand I'd like to avoid ordering some if at all possible.

 

I have made one too. Makes it run quiter as the fans dont spin so often.

Most of us aren't ballsy enough to take it all apart, or at least I'm not. I feel totally fine with everything in desktops and just changing hard drives, ram, and other basic stuff, but CPU and GPU's on laptops scare me. Especially a 1300 dollar one I worked under minimum wage for all summer for...

 

Woah, that one looks awesome! What's holding it up? It's a cool brushed metal pattern.

 

Yes, re-pasting was the most cool-ing thing I did for this laptop.

Full load Dell paste

processor max 98c
graphics max 78c

Smart load IC7 Diamond

processor max 83c
graphics max 72c

Idle is about the same.

And in Bios it states that processor throttles down after reaching 85c, I changed that to 90c to make sure lol

And, I took out DVD drive, ram cover and battery.

 

Here's the lego one I built. I made it out of technic peices I had laying around. It has 2 openings in the rear left and right to allow for better cooling of the fan and ram slots. It also has feet on the bottom that keeps the cooler about half an inch off the ground.

 

Its just a laptop vinyl cover (15.1) with some plastic bottle caps mounted on it...

 

hahaha when i opened this thread up i laughed so hard, cause i used legos to lift up the back of my laptop when i play games too!!!

 

I think the most ideal stand would be something where it's like a solid rectangular plate with 4 cylinders 1" high on the corners with rubber on the top to grip the laptop. I find the Lego's don't grip very well.
