Thermalright XP-90 RT vs Zalman CNPS-7700cu.

The XP-90 doesn't come with a fan. You need to purchase your own.

This discussion has been had numerous times in this very forum. I'm not thread crapping, nearly suggesting you browse a little. All of the information, and God knows opinions, are available to you right now.

It is my opinion that you can't do wrong with either. I personally own an XP-90c, and think it's the best HS I've ever used.

My XP-90 came with a fan...I replaced it with a Panaflo, though. Anyway, I can personally vouch for the XP-90.
 
Definitely the retail XP-90 if you consider the $10 difference (if not more) between it & the 7700-Cu & are on a budget.

On the other hand, based on this article. The 7700-Cu is only 0.4 C degrees hotter than a XP-90 with a 57 CFM rated Panaflo. Since the fan bundled with the XP-90 is rated at 45 CFM, one could assume there's at least a 1 C degree difference between the 57 CFM rated fan & the one bundled with the XP-90 in cooling performance. Therefore the 7700-Cu would probably perform better than the fan bundled with the XP-90.

However, personally if I were in your shoes. I'd opt for the non-fan bundled XP-90 & combine it with a high CFM rated fan while still coming out cheaper than if I had bought the 7700-Cu.
 
The 7700Cu is much more flexible with the Fanmate 2 controller. No need to worry about adding another fan. The larger fan/heatsink will also cool other components like RAMs and MOSFETs on the motherboard.

Why bother with the Fanmate at all? Any modern system has the ability to control the speed of the CPU based on temp, if you want even more control there is SpeedFan.
 
-Most boards will only take down the voltage to 7V. Fanmate 2 can be used with the motherboard to lower the voltage to 5V.

-One can instantly override the speed using Fanmate.

-SpeedFan must run in the background and is not 100% compatible with ALL boards.
 
XP-90. especially since it easily fits on every board, and cools better. also, you can choose the fan and easily replace it.

I doubt the xp-90 fits EASILY on every board.

Other than the concurrent cooling of RAM, Caps, MOSFETs, etc. (due to 7700-Cu's girth). Who's to say you can't buy a Fan Mate 2 or similar for any other aftermarket heatsink/fan combo.

Alright, could you recommend a92mm high cfm fan thats less then $10 shipped? Is there any?

Panaflo H1BX (FBA09A12H). 56.8 CFM, 35.5 dBA, 2,850 RPM. Supports fan-monitoring function. $8.00 when ordered with the OEM XP-90 ($24.95), so you're talking $32.95 plus shipping. Great performance and cheap too. The XP-90 comes with the fan mounting clips and AMD mounting bracket. Check out the specs on the fan here:

or a Medium speed Panaflo (48 CFM, 30 dBA, 2,450 RPM. No fan-monitoring. Link:

http://www.jab-tech.com/customer/product.php?productid=2044&cat=80&page=1

or the low flow Panaflo L1BX (42.7 CFM, 27 dBA, 2,100 RPM. Speed monitoring. Link:

Heres' the link to the XP-90:

Just click on the drop-down menu when you order and you can choose which fan you want
 
thanks man. is rpm monitoring even importnat though or the type of connection if I were to buy a different fan...like a 4pin/molex instead of the 3pin cpu?

The 4-pin Molex is for a direct connection to one of the PS connectors. This will have your fan run at full speed all the time. If you run the fan off the mobo header and enable the Smart CPU Fan option in the BIOS (I have an MSI K8N Neo2 mobo, I think Asus calls it "Smart Fan") the mobo will actually throttle down the CPU fan speed at idle (or anytime the CPU is running cool and doesn't need full speed).

Some fans come with 3-pin and 4-pin connections to give you the choice of running off the mobo (or fan controller, ect) or directly off the one of the PS leads. As I said before, I like to run off the 3-pin mobo header because I like to let the mobo control the CPU fan speed.

RPM monitoring isn't important unless you like to be able to keep track of the CPU fan speed (which I do). The fan spped can also be a rough gauge as to the health of the fan - if it starts acting flakey its' usually time for a new one.

Obviously you can't run your PC without a CPU fan running or you'll fry your CPU. If you monitor the behavior of your CPU fan at least you can get a replacement fan ordered and on the way so you can replace a defective fan with minimum downtime.
