Is the Cooler Master Hyper T2 ok for overclocking?

I recently bought the i5 4690k and I overclocked it to 4.0GHz with the CM Hyper T2. I did some stress testing on Prime95 and IntelBurnTest and the core temps were way too high (like 80-96 degrees celcius). I was wondering if my CPU cooler was the problem or the overclock itself? Thanks!

its the cooler, you will need something a little bigger, like the CM 212 or maybe a liquid all in one, I like corsairs liquid coolers, there are a few other brands out there too, CM make some good ones

Well it honestly should be fine for a 4Ghz overclock, the temps sound really friggin high, even for a stock cooler. Is voltage on auto?
Did you apply your own thermal paste? Something is wrong, I know the t2 isnt a very great cooler, but it should be better than your current performance.

When I overclocked it, I put the voltage on 1.4 but I put it back to the stock settings because of the extreme heat. Yes, I did apply my own thermal paste.

That's silly, there is no way that the TX3 should perform worse than the stock amd cooler. I have a 8370E, 6300, and a 760k, the 8370E gets 49c under Prime95 for 2 hours with only the stock cooler. Shocking, I know, but I think the lowered TDP on the "E" versions really helped. The 6300 topped out at 65c under prime95 with stock cooler. I am about to install the T2 on the 6300, I will update you guys on the results. I expect at least 10 degrees drop under max load.

When installing new cooler, make sure to completely clean off old thermal compound. I got the Arctic Silver 5 because I don't trust the stuff that comes with the CM hyper t2. Also do a good job applying new thermal compound. There are guides for that if you're unsure.

Update: just installed the CM Hyper T2 on my FX 6300, max load went from 65C to 49C with ambient temp of around 25C. With Arctic Silver 5, this cooler performs very well for the price. It is more effective and quieter than the stock cooler and should be able to handle light OC. You ought to get some Arctic Silver or other reputable thermal compound and reinstall the cooler, as well as lower your voltage.

There is no problem with the cooler or anything, stress tests are pushing the CPU to it's limit so it will heat up a lot no matter what. That cooler is fine, my 4690k with stock cooler hits 100 degrees on stress, I know this is terrible, but you should be fine.

I have a CM Hyper T2 and the i5 4690K OC'd to 4.5GHz (45 CPU multiplier). When I stress test with Prime95 (small FFT's test for max thermal stress), my max temps are about 76 degrees Celsius. I have my Vcore voltage set to 1.170 and I had my CPU Cache ratio multiplier set to 43. If my Vcore voltage was up to around 1.3 volts or so, then I'd be into the 90's under load. I had to use manual settings because the automatic overclocking on my Asrock motherboard set the voltages way too high for my liking.

EDIT: I also have 5 case fans. I forgot to mention that. Two in front, Two in back, and one on the side.

I know this is an old posting but i got to ask when you placed your cooler for the first time did you take off the protective plastic seal on the bottom because some people makes that mistake which does result to overheating.
