Heat -Sink & Fan

Here is a link to a very good web site with a lot of useful information about cpu heatsinks:

You can use the Google embedded search feature at the web site to find more information about heatsinks for specific cpu sockets.

The Sigma Shark 625 watt power supply is not one that I am familiar so I checked several technical reviews:

It is not what I would consider a stellar performer but it should be okay for just one video card. The first thing I noticed was the 110 to 240 volt switch on the rear of the unit. Modern high quality power supplies are able to automatically change voltage without a switch. The next thing I noticed was the current (amps) on the +12 volt rails. The +12 volt rails supply power to the cpu, video card and some other components. The current on each rail is rated at 20 amps. The actual combined total will be a little less that 40 amps. That is about the equivalent of a high quality 500 to 550 watt power supply. I would have expected the combined total current for the +12 volt rails to be rated at 50 amps. Finally, the psu only comes with two, 75 watt, 6 pin, PCI-e power connections for video cards. A high quality 600 to 650 watt power supply would come with 4 PCI-e power connections. In all probability the Sigma Shark 625 should be considered as an average 500 to 550 watt power supply.

there are so many coolers that will do the job, it really comes down to personal preference. the scythe mugen 2, TRUE, or Tuniq tower 120 extreme are all very good choices.

id say see what you can get locally at a good price, check some reviews and choose from there.

Thanks JohnnyLucky.

I have looked on frostytech & Heatsink factory both. My issue is which one(s) would work best with the Corsair fan Kit and the GPU in the same general area. It seems their might be limited space around the CPU. Looking for similar conf. to compare to.

Yes, I know the the PSU is pretty sketchy. One paycheck at a time.

I was thinking of a Rifle rig as well. Not sure about the fan clearance.

My local shops disappointing. I am tied to the internet for good gear.

Hey JL, This is what I came up with. I owned a Cooler Master V8 and sold it. Too much of a strain on the MOBO.


1. Heat sink & Fan - I thought one these would do the job.

Thermolab Baram Universal CPU Cooler

Thermalright Ultra-120 Extreme Rev. C CPU Cooler


2. PSU, I have narrowed it down to these.

Antec EarthWatts EA750 750W Continuous Power ATX12V version 2.3 SLI Certified CrossFire Ready 80 PLUS Certified Active PFC

CORSAIR CMPSU-750HX 750W ATX12V 2.3 / EPS12V 2.91 SLI Ready CrossFire Ready 80 PLUS SILVER Certified Modular Active PFC

Thermaltake Toughpower XT W0229RU 750W ATX12V V2.3 80PLUS BRONZE ATI CrossFireX Certified AMD GAME READY FanDelayCool Modular Power Supply

Thanks in advance for the help.

I am new to the forum and appreciate the quick responses. I know you can see my Newcomer badge and chose to ignore it. Thanks for that as well. You offer the most qualified answers I have seen yet. I hope to repay the debt of knowledge someday.

I have the original Thermalright Ultra 120 installed in my HAF 932 case. The Ultra 120 Extreme is a new and improved version.

The Corsair HX750 is a brand new psu that earned a Silver certification for energy efficiency. It also has modular cables so you only use the cables that you actually need. It makes for better cable management and improved air flow inside a case.
