Is 25% oc too much for stock cooling?

[htoonthura]

Hello

I have my friend's E4400 processor overclocked from 2.0 to 2.5 on stock cooling. The pc is running stable during and after stress tests. As a matter of fact, i have never seen bsod with that machine. Although it is perfectly stable after 5 hours of stress test, the temperature can shoot up to 75 during the stress test. The stablity test result can be difficult if i let it run for more than 5 hours. But, I do not want to run a cpu that hot for long time even though it does not crash. Besides, my friend will never tax his cpu that much. My question to you is that " Do i need to put extra fan to keep it cool down and run the stress test longer or Should i be complacent to the current result knowing that he will never stress his system as much as the stress test can do for at least 5 hours?

Thanks.

Thura.

I think you need to reseat your stock heatsink as i've heard people overclocked their E4400 to 3GHZ with stock cooling. 75"degrees is unacceptable if you're talking about 75" celcieus, but if its farenheit, then its fine. 2.0GHz-3.0Ghz should be a mild overclock thus if you've seated the stock HSF correctly, you should be getting 60~"degrees celcieus under load in TAT.

Yup, what jackluo923 said is correct.

If the temp is in Fahrenheit, then you're okay. If that's in Celsius, I would go back to original speed, and check temps there. If you're still hitting 75C, then something is wrong.

Again, what jackluo923 mentioned is correct. With a minor oc, you shouldn't be pushing close to 70-75C at all.

Sorry about taht
I said:

It should be 2.0-2.5 as you said before. But overclocking at 3.0Ghz using Stock cooling should give you 60~"degrees celsius( which i spelled wrong earlier because the spell check isn't on)at full load.

too little

this is a very good question!

basically all chips are the same - by that i mean: if someone sells a 4ghz core 2 duo then 4 ghz is the max

if you buy a 2ghz chip then 100% oc is possible
if you buy a 2.92ghz chip the 33% oc is possible

the secret to oc is to buy the right chip at the lowest price - now its a an e6600 soon to be a q6600 on 7/22

a q6600 will run 3.3ghz with out a sweet on the right mobo
