Temps for folding with i5-2500k

post #1 of 6
Thread Starter 
So I've been trying to get a 4.5 GHz clock on my i5-2500k lately and I ended up having to raise the Vcore a few notches to get a stable clock from 4.4 - 4.5. My temps now are somewhat high and I was wondering if these are considered safe for 24/7 (maybe not quite 24/7, but that's the goal) folding. I would like for the life time of this processor to be at least 4-5 years. I have a Coolermaster Hyper 212+. Here are my temps at 4.5 GHz:

Idle: 38 - 42 C
Full Load: 65 - 72 C. The absolute highest any of the cores read on Core Temp after a couple of hours was 74 C.

At 4.4 GHz the temperatures were about 5 C cooler at stock and full load since it ran fine on 1.3v (had to raise it to 1.33v for 4.5 GHz).

On a side note, are these temperatures too high for an overclocked i5-2500k and my cooler? I've read that some people are able to get to 4.5 GHz and keep the load temps below 60 with my cooler, is this true?

Temps sound about right. I have the same cooler on my 2500k and it's about65-70C. Low 60s might have a lot to do with ambient temps and air flow. Could also do with emblellishment.

Those temps look alright. As long as you keep them under 90C (98C is an aprox.) you're chip should run fine. My 2600K runs at a max of 74C while folding.

My 2500K gets to 74C while folding at 4.1GHz... at stock cooling!

The temps seem to be in line with what other people are getting on their 212+. Ways to shave several degrees off your temps:

- Use good paste (OCZ Freeze and IC7 Diamond are popular choices, will run around 5 bucks a tube)
- Use the correct amount of paste
- Replacing the stock fans on the 212+ with something like YLD12SH. You can pick up a set of 4 for $20 + shipping from Petra's Tech Shop

I would say that the main cause of your higher temps is the lack of airflow. The Sonata looks nice but there is only 1 rear exhaust. Opening the side panel should also drop you several degrees, although you would be dusting up your case at a quicker rate. I also see two side intakes but I am not sure if they support fans.

Thanks, I just ordered some Arctic Silver 5 although I sort of regret it after hearing about it being conductive and not recommended for anything other than the CPU heatsink (so no GPU). Does replacing the stock fan on the 212+ really help? I would rather not spend another $20 for a 1 or 2 degree drop but hopefully the better paste drops it more than that.

It turns out that my CPU was not 100% stable after running prime95 for a few hours, so I raised the VCore even more but that doesn't seem to have raised the temperatures any further (still testing it).

The side intakes on the case are placed where the hard drives go so they don't technically support fans. I agree that the airflow probably isn't the best in that case but it's good enough for me .
