What cpu coolers work best for overclocking with AMD cpu's?

 

I need help guys. I can't seem to get my FX-8350 temps down low enough to be comfortable with overclocking it. I want to know what success you guys have had with coolers and overclocks with Amd cpu's.

 

 

Current Cooler

Corsair H55 liquid cooler

Stock Corsair fan 1700rpm (although it's more like 1500rpm)

Artic Silver 5 thermal paste

 

Current Temps (stock speeds)

idle: 23-27C

Load/Stress: 70-75C

(These temps seem kind of high to me especially considering those temps are at stock speeds.)

 

 

Some things to consider:

I use a test bench (in the pic attached, I was too cheap to buy the Top Deck Tech Station so I built my own), so size isn't a huge concern and case doesn't affect temps. I have a Noctua NF-F12 fan that I will be getting today (although I don't know how much that will help). Cost doesn't matter however at this point a custom water cooling loop is not ideal and the cheaper the better.

 

 

Any suggestions for which cooler I should use and the temperatures I should expect would be awesome! Also, personal experiences with specific coolers and overclocking are definitely welcomed.

 

As a side note: PLEASE FORGIVE ME CABLE MANAGEMENT GODS, FOR I HAVE SINNED! (The cable management is temporary)

This is exactly the type of thing I was hoping for. I never would have thought to add a fan on the other side of the motherboard!

 

That's a pretty nice overclock. Are you worried about the voltage at all? I've only overclocked intel cpu's and I was under the impression that anything over 1.3 volts is in the risky territory.

Stock voltage for the FX is 1.4v+ (can't remember, I haven't had this at stock for over 2 years now...) There has been some people pumping 1.7v into their FX chips to push their clocks but tbh that needs chilled water or LN2 because I simply struggle to keep my VRM and CPU cool with a 360 and 240 rad. You need to keep the VRM cool because that keeps your Volts and Amps "clean" (no ripples and fluctuations that cause instability) but your board will limit your overclock quite a bit, you'll probably be stuck around 4.7ghz or a touch more.

Stock voltage varies with bin, it's up to 1.4 but standard turbo rate is 1.4125 and 1.425v

 

But yes I had to put a fan on the VRM and back of the socket when I was pushing 5Ghz+ for benchmarking.

Same.

I will put a fan on the back of the socket tonight and overclock depending on the temps.

There is a metal plate on the back of my board, do I keep that on there with the fan or should I remove it and add the fan?

 

Also, could the recent application of thermal paste on the cpu be the cause of higher temps? I know some say thermal paste has a "break in period" or "bake time".

Keep the metal plate it's holding the cooler on  ;)  Also you might of put too much TIM on or not enough. Possibly your ambient temps have gone up.  :)

Haha, what I failed to mention is that the cooler came with a plastic back that covers far less of underside of the socket. I will check to see if I added too much or not enough. Thanks for pointing that out.

Put the metal one back on, Fast fans on the socket and VRM.
