What is the best heatsink for a Core 2 Quad?

I would recommend the Thermalright Ultra-120 eXtreme, from my research it's about the best you can get with air. I'm currently using a Zalman CNPS9700 LED and have been able to push my 2.4 ghz Q6600 Rev. G0 to 3.6 ghz. It's running 35c idle and around 55c load. I will soon be getting the TRUE cooler though, and adding a Sythe S-Flex 120mm (Ultra High Speed). www.xoxide.com has the TRUE heat sink and Sythe fans on sale.

now if only you can find the TRUE somewhere. The egg never has it in stock.

 

I've also heard from people on here that the Tuniq Tower is supposed to be good.

The Thermalright Ultra 120 Extreme is the best air cooler on the market right now. It is somewhat tall, so make sure you have a large enough case to house it. They also have a tendancy to come with slightly warped bases so you may have some lapping to do:

Notice I also opted for an additional fan attacked to my heatsink to suck in the air. I honestly believe that alone was good for a 5-7 degree drop. I used a Scythe S-Flex fan. The True comes with fan clips, but they can be a pain to install. I may also be adding another fan to the other side of mine to pull the air out. Just make sure you have the fan installed the right direction. When I lapped my heatsink, I wasn't paying attention and put my fan back on backwards :blush:

 

 

A shorter option to the 120 is a Noctua NH-12F like I used on a friends rig:

It was about an inch shorter and I was able to put a fan on the side panel to aid in the cooling. So far, it's keeping his rig in the 30-33 range at idle and in the 50-57 range under load. I used Arctic Silver 5 on his. The Noctua's base on his was copper and came perfectly flat. No lapping necessary.

 

 

 

The heatsink you choose will all depend on the size of your case and how much room you have to work with. Motherboard components as well as your memory sticks can get in the way sometimes as well.

 

 

 

Good Luck B:)
