As a follow up to the Heatsink Roundup on C2D, I've got another batch of tests using a Core2Quad Q6600 CPU, I've got twelve coolers in all being tested.

I've eliminated a couple coolers I used for the C2D roundup though as they were not adequate to cool the C2D so they would not be able to handle the C2Q, but I've added Liquid Cooling and the Thermalright Ultra 120 eXtreme to the testing charts.

The same as before, you'll find testing involving the fans connected to the CPU header, connected to a Molex and of course coolers that are able to use no fan at all.

For testing I've got names like Thermalright, JetArt, GlacialTech, Corsair, OCZ, Scythe, Noctua, Coolink and the Intel Stock cooler.

To make all testing even I used Arctic Cooling MX-2 thermal compound on all coolers.

This little roundup has been a while in the making so jump on in and see what's going on...

EDIT July 10th:

There's a total of 18 now in our testing charts for comparison from various companies including: Kingiwn, Noctua, Corsair, Coolink, Thermalright, Jetart, GlacialTech, OCZ, Scythe and of course the Intel Stock Cooler

C2Q Q6600 Heatsink Roundup -18 Tested

Author: Kristofer Brozio

Sponsor: DragonSteelMods and Arctic Cooling

Test System Specs, Testing Procedures and Basic Info:

All testing was done in a controlled room temperature environment that was always at approximately 19C with a +/- .3 degree variation. All effort was taken to insure a controlled testing environment.

All testing was done using the Arctic Cooling MX-2 Thermal compound, after every test the CPU/Coolers were cleaned with Arctic Silver ArctiClean to insure proper testing and good thermal conductivity.

Arctic Cooling MX-2 Thermal Compound

Turbo MX-2 is a high conductive and low resistance compound for components that require the best thermal dissipation. MX-2 is ideally suited for use in CPU, GPU cooling and other applications between power semiconductor components and heat sinks where high thermal conductivity is critical.

My test setup consists of:

Intel C2Q Q6600 CPU running at 2.4Ghz

(-no overclocking was done for testing)

Gigabyte GA-G33M-DS2R LGA775 Intel G33 Bear Lake mATX Motherboard

2gigs of OCZ SLI Ready PC2-6400 Ram

Connect3d X1800GTO Video Card

1x Hard drive

1x DVD/RW Drive

Ultra X3 800Watt Power Supply

all housed inside of a Thermaltake Matrix VX PC Case with two 120mm cooling fans (1 intake/1 exhaust)

I used CoreTemp v.96 to get the temperature readings, I enabled the logging feature and averaged out the temperatures to get the results that you will see in the charts on the following pages.

To achieve load on the CPU I used Orthos Stress Prime, I basically turned it on and let it run for 3 hours at a time, this was done over several days to insure accurate results. Two instances of Orthos Stress Prime were used with Affinity set to two cores for each instance.

To get the idle temps I turned the system on and let it sit running nothing but the Windows XP processes for an hour, this was done over several days as well to insure accurate results.
