Antec Kuhler H2O 920 with AMD FX 8350 a little too hot

I have an Antec Kuhler H2O 920 on my AMD FX-8350 but my CPU temperature was about 48 C idle and about 53 with just normal use (no gaming, just web browsing) and it gets higher at around 60 when gaming. Is it just normal for 8350? I thought people could get their CPU at around 25 degrees when idle and around 45 with full load... Should I get a new cooler?

When I first bought the Antec Kuhler H2O 920, i wasn't actually happy lol. the back plate was like a crappy cheap plastic thingy. And it turned out to be not that good as expected, i was not able to screw off one of the screw because the plastic plate wasn't strong enough to hold the cap and the cap kept spinning as I was trying to take out the screw.

Anyways, I did that because I wanted to check the thermal paste. So I reapplied the thermal paste with the dot-method. The temperature remains the same.

Is this normal to the FX-8350? or is there a problem with my cooler?


By the way, the cooling was efficient for me to play games but my fan soon reaches the highest setting and started to be noisy.

And for many of you may ask, I didn't overclock my CPU at all. Nothing was changed. Everything was on stock.

That's not right! 63 ~ 65ish temps are the higher you should go. The cooler is pretty good you shouldn't get those temps. Try following the instructions again and if that doesn't work then request a new one or something.

I did it again, it didn't help.

But I found something that may possibly be the problem.

Before I have my FX-8350, I used to have a Phenom II X6 1055T but I applied too much thermal paste which it eventually leaked into the CPU socket and on the CPU's pins as well. I cleaned it with the 91% alcohol and the help of a tooth brush, i got them cleaned on the CPU, but the CPU socket still have a tiny bit.

the Phenom II X6 1055T worked fine without any problem though. could this be the problem possibly?

I don't think so. If the thermal paste could conduct electricity it would fry your cpu instantly. I don't believe that it is an issue. Since your cpu works the thermal paste located in the pin sockets won't matter. Try putting the Phenom II X6 1055T in it to see what temps you get. Might be the cpu my friend.

Unfortunately, I sold my old CPU already. But I remember when I had my old CPU with an Cooler Master Hyper 212 plus, the temperature goes around 30C on idle and around 50 at full load. I switched my CPU and the water cooler at the same time though.

I just tried it. The temperature doesn't seem like it's going to go down. It's at 47C now. with nothing actually running excpet this Tome's hardware web page. I also noticed the Vcore 1 and Vocre 2 is also high. it's at 55C and 51C and at 65C for both while gaming. (the warning notice even shows up because it reached over 60C from my AI Suite II)

Best solution

I really believe your cooler has some serious issues. Do you have the stock cooler or something else so that you can cross out the cpu or the cooler!

dont use that cooler
return it or buy a new cooler like the amazing hyper 212 evo for 30$ that would give great results

I was actually wanting someone who has the experience with FX 8350 and is running a somewhat similar cooler that has significantly lower CPU temp then mine to reply to this post so I can confirm that it is sure not the CPU's problem.

and btw. Sn1992 why not to use this cooler? Is this product bad? I've read some amazon reviews though. it is not the best, but it certainly not a bad product.

ITS A FAULTY PRODUCT MY ADVICE
my advice it to contact antec support
and i have installed few of these in my client builts the temps never crosssed 57 on stocked voltages even when running prime

The problem is found! It really is the problem with the cooler. I guess it's defective or something. I changed the cooler to my old Hyper 212+. I ran prime95 and the temperature never goes beyond 48C! Thanks for both of your help. I would have to select the first guy who helped me first :(
