i5 2500K way too hot - Need advice!

post #1 of 19
Thread Starter 
I just built the below SFF gaming rig and I'm topping out at 73c at stock speeds when running IBT and obviously higher when I attempt an overclock (I stopped IBT when my CPU hit 80c at 4Ghz). I've reseated the cpu cooler, installed more case fans, and am not sure if I should try anything else or just throw in the towel and just run at stock speeds (I assume I'm "safe" at 73c under load at stock even if not ideal). Am I doing something wrong or is it possible that I just got a really hot cpu? Here are my specs:

Lian Li PC-V354
Asus P8P67-M Pro
i5 2500k @3.3ghz
Noctua NH-U9B SE Cooler
8 MB ripjaws ram @1600mghz
MSI GTX 570 twin Frozr III
Intel 510 120GB SSD
Samsung Spinpoint F3 1TB HD
Corsair HX 850W
Asus DVD Player

I replaced the stock LED intake fans with 1200 RPM Scythe Slipstream fans and added a rear exhaust Scythe fan, but I kept the stock 140mm top exhaust fan. Would love to be able to overclock this, but I'm not even entirely comfortable with my temps at stock speeds. Any advice would be much appreciated!

Try a different Thermal Paste. I reccommend Arctic Silver 5. If it still gets wayyy to hot, then you might not have enough of a good cooler or just a hot CPU.

Have you had a look at reviews of your cpu cooler? Does it match up with other online reviews?

Are you using AVX when running IBT? 'Cause then IBT is a baaaaad idea.

that CPU cooler is more then capable of cooling your chip. I would have to go out on a limb and say that you need to reseat your cooler.
are you using the stock paste that came with it? if not, get something better like AS5 or ic diamond.

Yeah, I'm using Noctua's thermal compound (which got great reviews) and have already reseated the cooler once. I have some AS5 lying around, so maybe I'll try it.

Perhaps I'm applying the compound incorrectly (although I've never had issues with previous builds). The first time, I smeared a very thin layer of compound on the CPU. The second time, I just put a small bead of compound in the middle of the CPU and dropped the heatsink on top of it (which is what Noctua recommends). Am I doing this correctly?

Yes, most likely.

Dont bother with a reseat, go in your bios and set the voltages. Your probably pulling 1.4-1.5v on stock settings, thats why your chip is getting so hot.

Here is a thread that will help you out with this board.

Then you probably aren't using it. AVX are some new instructions that SB can use. In IBT they make your CPU ~10 C hotter than the normal IBT. You'd have to install them manually, so you don't have them.
