Intel Core i7 3770K and Corsair H100 running too hot? - Page 3

The temperature of the GPU dropped from 78C to 77C, and that's it.

Okay, I figured out why the CPU temps are so high.

It's just what some of you have suggested, and what I was beginning to suspect: I applied the thermal paste incorrectly.. haha
I spread it myself, yeah, I'm an idiot I know.

Plus the paste I used wasn't the greatest quality I suppose. So I'll be re-applying it the correct way with better quality paste tomorrow.
I'll post the results tomorrow.

Now as for the GPU, it's because the air cooling in the 800D case is horrible. I need to find a solution for that still.

just try the pea method and let block spread it, or can use any of various other ways. mx-2 always a good choice

Here is my long winded advice on TIM (aka thermal paste) application from another thread:

I was testing with AS5 because it is cheap, easy to use, and easy to clean. That was helpful in my 30 or so tests of mounting a cooler to an IHS. No two coolers are the same, and no two IHS are the same, therefore there is no "best" way, only what is best for your setup.

I have tested three 3770k, one Antec cooler, and two Corsair coolers. The best way to know is try different combinations and different amounts of TIM. Then there is orientation of the cooling block, and how you tighten it down (not only how tight but which screw in which order). For example, in my current setup the best solution, by far, is the cooler block upside down and screwed down at the top first.

So you try single drop, line, spread, and each one of those can be varied as to how much. Additionally there are usually four positions for the cold plate orientation of your cooler. Each test you check temps and then look at the "fingerprint" that the TIM leaves on both surfaces. You will quickly discover that fingerprint tells you a lot about how effective the cooling will be.

(this part is for delidded folks - but shows different amounts need to be tested to find the best one)

I also found that you can absolutely use too little Ultra on the die. There was so much talk about everyone using too much, I tried multiple times using less and less. Too little is very possible to do, so you just have to test it. This again is chip dependent because the shape of your specific IHS will determine the optimal amount of TIM to be used on both the die and on top of the IHS.

The proper amount on the die is more important than the proper amount on top of the IHS though. But most people don't care about a few degrees either way, so as long as you get the TIM application on the die as close to perfect (for your particular chip) as possible, then you will get the best results. An OK application on top of the IHS vs. a perfect makes a difference, but not as much as getting right with the TIM application.

Isn't there a fan in the bottom of the 800D? That case seams enormous, for the amount of hardware inside it :S. The 680 should NEVER reach those temperatures.... not even overvolted... If it runs equally hot without the side panel installed, i would RMA it, cause that is just.... wrong.

Agreed. With the side off and just sitting at idle in a 75f room, that temp seems way too high

Okay everyone, here were my findings...

Re-pasting the CPU worked wonders on fixing the heat issues with the CPU. Idle temps were between 24-34C on average, just as they should be, and prime95 temps were around 55-63C I believe. That sounds better than before.

Of course, those temps were without the GPU in the system. I put the GPU back in, and my temps rose again, and the GPU is still around 77C...

I called EVGA, and once I told them that the card was idle at 77C, they immediately agreed to RMA the card. We'll see what happens with this new one.

EVGA is really good about their RMAs. Hoping to hear your replacement card has some different temps thumb.gif

I'm hoping so too. This is really disappointing, but what can you do.

Those temps from the CPU without the GPU in the system have really improved, so at least that issue is resolved. Just hoping a replacement 680 fixes the card heating up to insane levels.

Great news! I believe that the problems with heat have been completely fixed, and I didn't even need to RMA the card!

Take a look at these temps for my CPU and GPU. This is idle:



And this is after Prime95 has been running for awhile:




So as you can see, the GPU hit 56C once during Prime95, but then it consistently sat around the 34C mark. The CPU during Prime95 was around the temps that I was getting at idle before when problems were happening.

What do you guys think? I'm thinking that my problems are over. thumb.gif
