IDK where to post this

Im going to buy an Asus Rampage Formula do i need more extra motherboard fan for this motherboard?

Im going to use Intel Core 2 Quad Q9450 Quad will Zalman CNPS-9700NT
do the job in providing cooling in the CPU and will this CPU FAN fit my motherboard?

This is the number that you want to beat.
Thermal Resistance: 0.17°C/Watt
Anything higher is a waste of your money.
If this number is not given, move along.

Oh by the way this is from the Arctic Cooling Freezer 7 Pro, $32 retail.

Everyone yells Zalman Zalman Zalman, well guess what I don't find any Thermal Resistance information on thier
web site or in the coolerss manuals. They are over priced anyways.

XIGMATEK HDT-S1283 120mm Rifle CPU Cooler
Thermal Resistance 0.16°C/Watt
$44 shipped

$10 for .01 Degrees C/W at best a cooling of 2 Degrees C, to me it's not worth the hassle of install and expense.

Scythe SCINF-1000 120mm CPU Cooler Thermal Resistance unknown price higher than prior units of know capability.

Tuniq Tower 120 P4 & K8 CPU Cooler
Thermal Resistance 0.16 - 0.21 °C / W from web site, $57.58 delivered.
Again over priced and a pain in the ass installation.

Bang for buck winner here, the Arctic Cooling Freezer 7 Pro.
Why bother with anything else?

A post script to the above:

XIGMATEK has a new unit out the Xigmatek Achilles S1284 for $45 before shipping.
Thermal Resistance 0.14°C/Watt
This may be the new big boy on the block.
$52 shipped from;

With installation of the XIGMATEK' being so problematic and almost requiring the extra mounting bracket,
that costs an extra $10. I would still go for the Freezer 7 Pro.

Yes it will work, might not be the best but way better than the stock cooler. And imo, zalman makes the best looking heatsinks
@bobknight, there may be no therm resistance on the 9700, but there is on the 9500 which is 0.12-0.16C/watt, the 97 is a 95 with heatpipes

well as mentioned above, if you wanna go with air cooling

the Xigmatek S1283 and TRUE are the best.

i would go for the Xiggy myself, the 9700 is a very nice looking cooler (thats why i bought it :p) but the fan is noticeably loud when its on full blast. when i turn up the fan settings for the 9700, i hear it louder than all my other fans in my case combined. :T

or you could always go with a phase changing cooler for lower temps and no noise.
