Intel 4790k 100 DEGREES!?!

post #1 of 86
Thread Starter 
Hey so i recently bought a new rig,

Apparently my 4790k was running 100 degrees on load with a stock cooler.

Reading the intel forum apparently 100's of people have that problem.

So i RMA'd it and they told me they could not replicate the problem.

At first i thought it was my Gigabyte Z97X - SLI motherboard.

But after reading more i saw everyone was having the same problem.

Now i finally got them to RMA my chip.

I'm wondering if the problem persists... should i DE-LID the IHS of my 4790k?

Should i try a risky BIOS flash?

I know stock cooling is crap.. But i'm going to buy a hyper evo, but i've even seen people have this problem with corsai watercooling.


What to do !

Wow, I have had the 4790K for months and didn't break 64°C at 100% load like ever... and that is on watercooling...

100 deg load with stock seems right

try the 212 first then delid if you think you need more cooling performance

liquid metal you can use for IHS example is this: http://www.performance-pcs.com/phobya-liquid-metal-thermal-compound-paste-lm-1g.html

Did you try remounting the heat sink cooler before getting an RMA? Thermal compound replaced? Could have been insufficient pressure for the contact of the heatsink to the chip.

Some replies.


@TK421. 100 deg on load is NOT right,

https://communities.intel.com/thread/54032?start=30&tstart=0

alot of people have the same problem because of the IHS not making contact to the DIE .

I'm gonna try the 212 with this new chip that ill get tomorrow.

Otherwise i will delid.

@RocketAbyss. I remounted the heatsink 5 times checked all those things

Putting the 212 evo straight on the DIE without IHS?

Why not put the IHS on the DIE without glue. Just to be safe.

Not scratching the DIE. Not exposing the PCB.

Look i just want to get my bloody 1500euro PC to work.

I'm not looking for trouble tongue.gif

A few things that I have tried when I had this issue would be:

1. Disable hyperthreading
2. Check thermal paste, if it isn't "splitting" when you remove the cooler, something's wrong.
3. Make sure the CPU is making contact to the cooler, and that there is pressure.
4. If all else fails, put a fan on the side of the case, of which would blow onto the heatsink.

Also, here is a picture of how much thermal paste you really need, in case you decide to re-do it, as a "pea" size is quite ridiculous.

What are you using to get 100C? If it's prime95? Stop using it. Use a other stress testing program such as Aida64. Prime95 puts too much load and can damage cpus.

Use old versions of P95 from 2011 that have no AVX/ FMA support. I'm using that and getting 80C on a poorly mounted h100i on my 4790k. That's at 1.28Vcore, 1.93VCCIN.

If I were to run the latest version of P95, that'd top 90C in a jiffy.
