Hello all. So recently i purchased a Coolermaster hyper T4 CPU cooler to replace my current stock AMD FX 8350 one. Everything went well during install but after booting up everything seemed to be performing much worse, including temperature which had been bumped up another 5 or so degrees, making it around 55-60 degrees whilst idling, and 70 or so degrees under load. I've been told that it might be that my 600 watt (don't know the brand, sorry :/) power supply just doesn't have enough juice, but as the power consumption between my old and new cooler is ~1 watt, i feel like this isn't the case. Any help would be really appreciated :)

Other specs:
AMD R9 270
AMD FX 8350
1 TB HDD (don't know brand :/)
16gb DDR3 Corsair Vengeance RAM
ASrock 970 Extreme3 R2.0 motherboard
600 Watt PSU

Thanks in advance :)


Also, i am unsure if this is helpful or not but after installing the cooler i attempted a screen recording, and only got 2mbps write speed, when my harddrive is normally capable of 120+.
All performance was regained upon installing the stock 8350 cooler by the way, which also makes me think it has something to do with the PSU.

If you're saying that everything was working fine or even better with your previous fan, and you upgraded, it sounds like your thermal paste between the CPU and cooling device is a little messy. Remove your cooler, use rubbing alcohol and a piece of cloth or paper towel (Tissues can break apart easily and make messes in your case that are hard to clean) to clean off your current thermal paste on BOTH your CPU and COOLER. Then reapply doing your best to use the LEAST amount as you can, start off with a small dot, and use a card of some sort (Credit cards work awesome, but get a little messy) to spread the thermal paste around as much as you can. In this case A little is a lot more!!!

I'm not sure how a different fan (very little difference in power draw) would cause an issue. Maybe it wasn't tight enough in how it was mounted? Or the mounting of the cooler may have pressed unevenly on the cpu or something. Also not sure why the cooler with only a few degrees difference in temps would affect your hard drive transfer rates. Those things seem unrelated. I've heard of people running higher than 70c so it shouldn't have been throttling the cpu. I'm wondering if the return to normal performance was the cooler or just due to restarting the system. Maybe there was a hiccup during the boot process when the new cooler was installed. If 1w was enough to cause all those problems I'd think the system would be crashing on a regular basis.

My mistake, it looks like the 8350 will start to throttle after 70c (I'm tired) - so perhaps that was part of the problem. I'm still wondering if something went incorrectly during the installation. Here's a benchmark (different cpu, athlon x4 620) showing t4 vs 212 evo. The t4 failed the overclocked stress test and even though the two seemed fairly close the evo was much better at cooling when overclocked. Looks like the 212 evo can handle higher heat loads much better, so maybe the cooler just can't keep up?

Thanks for all the responses everyone! :)

I'll try re-installing the cooler (this time with less thermal paste) and see if that does the trick.

Thanks for the replies!

Edit: It's all sweet now and is working at the same level as it was with the old cooler. Thank you all for your advice :)
