i5-2500K OC'd 4Ghz on Stock cooler? - Page 2

Is this still safe or should I go back to stock? I know I should upgrade from the stock cooler but I really can't afford much right now. I have a old Xigmatek 1283 cooler with a thermaltake LGA775 bolt-thru kit and was wondering if that would be compatible?

I overclocked my i5 2500K on my ASUS P8P67 Pro to 4.4 using the ASUS TurboV program. My idle temps on all 4 cores is around 32c with the stock cooler. The fact that I don't have the side covers on might make a difference. I just built this system a couple of days ago and everything is running smoothly. I can probably take it quite a bit higher with better cooling.

Could I reach 4ghz with the intel stock cooler? Having great temps and not stressing it at all? I've read that 85ºC max in stressing and 80ºC in gaming should be fine.

I have added a Cooler Master 212+ heatsink with 2 fans since I overclocked to 4.4 with the stock cooler. I'm overclocked to 4.5 now and everything is running great. I can easily go higher but I'm satisfied with where I'm at. You shouldn't have a problem with 4ghz and the stock cooler.

I know that with a special heatsink I can reach far horizons but...with stock cooller without reaching stress temperatures that tortures it?

I don't remember the figures since it was back in March but I ran Prime95 for many hours and my system never overheated with the stock heatsink at 4.4ghz. The temperatures were safely under the danger zone. But instead of concerning yourself with over heating why not just buy a better heatsink? It's a piece of mind and protects your investment. The Cooler Master 212+ is well regarded and very reasonably priced. There are other choice too that are not that expensive.

I should have added as you probably know, all CPUs of the same model are not the same as far as overclocking. Some do a better job at overclocking than others. So your i5 2500K may not be able to attain as high a boost as mine. Or it can maybe do better.

I got TRUE 120 but I didn't got the adapter to let it fit with 1155 socket :S so I will need to use the stock one for a lil bit amount of time. Just wondering how to take care of it using just the stock one.

Just to remmember which were the maximum temperatures that I could reach doing stressing test?

Those temps are perfectly safe. However, that doesnt leave you alot of overclocking head room. If you plan on going any higher with the overclock I would strongly suggest an aftermarket cooler.

Even a hyper 212+ will give you better results than stock.

Given your chip does run a bit hot for 4ghz (even for stock cooler) this could mean a few things.

1. You haven't fine tuned the overclock and reached your minimum required voltage for that clock.
2. Your heatsink is mounted improperly.
3. You have a really good chip with a low stock vid. I have noticed with this generation, and previous, the lower vid chips tend to run hotter than the higher vid chips and they tend to clock better.

Also, ambient temps play a huge part in this. Its always best to have an accurate ambient temp reading when recording temps, or testing cooling solutions.

The original post was back in February so I'm sure he resolved it by now. Overclocker.Monster revived the thread with his question that's why it's active again. smile.gif
