High i7-2600K temperatures!

post #1 of 7
Thread Starter 
Hey guys,

I recently switched from a Corsair A70 to a Corsair H70 when they went on sale a little while ago, and I'm not noticing any improvement in CPU temperatures. Right now, after just booting up Windows, my ASUS AI Suite II reports my CPU temperature at 36ºC. When I was running the A70, my idle temperatures were anywhere from 27-30ºC...

Is this normal? I have yet to stress-test the CPU yet, but I'm kind of worried about doing that if I'm idling higher. Maybe something isn't working? If so, is there anything in particular to look for in the H70?

Thanks in advance. <3

Idle doesn't mean anything, Load temps?

You may want to try re-seating the water block. Also, are you running the fans with or without the undervolt? Exhaust or intake? What is your ambient temp?

I would definitely say you are OK to stress test the CPU. You should, to compare it to load temps on the previous cooler. I would say the idle temps don't mean anything - IF your load temps are still good.

Mine idles around 30-34C depending on ambients, which is totally fine because on full load at 1.27vcore (2+ hours prime) I barely crack 70C.

Wow, yeah, I am such a n00b. I totally forgot I had used the undervolt cables. And after running Prime95 for about fifteen minutes I'm hovering around 70-75ºC. I'll try it again with the undervolt taken off.

70-75C sounds about right with the stock fans running undervolted. The stock fans are a bit loud without the undervolt in my opinion, which is what has led myself (and many others on OCN) to upgrade to some aftermarket fans.

But to be honest, if you don't go above 80C after some serious stress testing with undervolts I think you are fine for most real-world usage.

You need to wait for the water inside the loop to heat up a little before your cooler will perform @ 100% efficiency. What's your overclock btw? My system runs much cooler even after 10 hours+ of Prime95 or IntelburnTest. And my fans speed are constant 30-40%.

The Noctua NH-D14 is a beast. 4.4Ghz @ 1.292Vcore, Highest temp ever recorded was 69C with IntelBurnTest. Coupled with the ridiculous airflow of my case the whole system is barely audible. The loudest fan in my system is the rear 140mm exhaust and I plan on replacing it for a more silent fan.

Hey Terry,

I am running at 4.6GHz at 1.35v. I am looking at having a little fun with the cooling on this H70 and picking up these:

http://www.sidewindercomputers.com/si50warh.html
http://www.sidewindercomputers.com/ststknforsi2.html

I am still glad I bought the H70 even after potentially spending a lot more money on fans and fan controllers (and a knob ;P), because it looks a lot better than some of those beastly heatsinks out there, and it enables me to upgrade my RAM in the future. There is no way in hell I could have fit any more RAM into my computer using my former Corsair A70, let alone the Turbulence II fans I have on the DIMMs.
