I5 2500k overclock temps too high?

post #1 of 34
Thread Starter 
Hey guys I'm just wondering if I should exchange my I5 2500k at microcenter. At stock speed with a thermaltake frio with Prime95 it max around 55C. (Idles around 32C-35C) While having it at 4.5GHz it runs 78C and 71C after placing some Xigamatek PTI paste on. (but all these temps were done with 100% fan speed about 2500rpm which is way too loud for normal use) I finally tried it at 4.8GHz with 1.395v and it idle around 33C-35C and the Max temp was 79C.

All of the tested temps and speed were only under prime for about 15-25 min. You think I would benefit from a new CPU?

After 4.6, you'll get more heat and problem than real world gain.
If you want to get better benching score, then go for as high as you can get to.
But for real world application, 4.6 is enough OC.
The temp seems to be fine.
SB throttles down around 95c and shuts off at 98c.

Go check out the Sandy Stable Club on my sig.
You may compare your set up with others.

Alright, but its just weird that the temps are about the same @4.5ghz and @4.8ghz which is about 78C to 80C. What is your idle/load temps for your 4.8 GHz?

it depends on the ambient temp.
AC on, 34~38. No AC 40~43.
Not sure why you asking idle temp... since idle temp means nothing..... unless it's ridiculously high like at 60c.
Load temp is the only thing that matters for OC.
And yours are fine.

sounds about right with the frio. had the frio b4 my h50 rma came (as a h60)
and my results were worst. around 78 prime blend.
now i get around 67c with 30 ambient

Alright, I was just looking at this(http://www.overclock.net/14041325-post1339.html) guy's i5-2500k overclock and its seriously the same settings as mine also the same amount of volts and just 100mhz lower than mine but the temps are 10C lower than mine and we have the same cooler.

Temps are fine, the Frio is kinda junk though, you would get similar temps with a hyper 212+ with fans in push pull without the loud vacuum noise the Frio gives off at full blast...I had the frio before when i first built this rig in january and even the H70 i had after it put it to shame, and the D14 i have now blew both away...

Take into consideration your ambient temp, his 10c difference is more than likely his ambient temp.
I dont know how microcenters return policy is, but if your chip is not defective, which it is not, then they will not just give you a new chip. Get a better cooler?

Well with 4.8Ghz it reaches 81C on prime and I guess I was just expecting lower temps from Sandy bridge (like 60C-70C max).

All systems act differently even someone has exact same set up as yours.
That is just how it is.
My chip is stable at 4.6 with 1.315v but it heats up more than someones 4.8 with higher voltage.

I mean you are 4.8 with air.
The chip is made to run at 3.3 stock.
So getting 81c on air is normal.
Just avoid going over 90c and you are fine. (you'll probably see 90c on IBT/LinX with AVX)

Every chip is different. He also could have used a different method of applying the TIM, or has better airflow in and out of his case.

May also vary on his mobo settings too?

Got my 2500k @ 4.5Ghz running 1.30vcore. Idle AC on - 28-32 / Load AC on - 60-62 ///// Idle 100+ Degree weather outside 38-41* / Load 100+ Degree weather outside 65-68 (Sometimes 70-71*)

I wouldn't really sweat it man unless YOUR worried about your temps. Maybe try a reseat or something, perhaps try to setup a Push/Pull setup if you can. Clean up your wiring a bit?
