Anyone ever put one of these in their mac pro?

My ram runs about 155 F and want to cool it down. I put one of these in my recent PC build, twin 2.5 ghz octo harpertowns, and it dropped the temp 30 degrees. Not sure if there is a spot on the mac mobo to plug it in though. Haven't checked yet. The ram is OWC. Cleaned everything and they still run hot.

Maxupgrades has their own solution. I've never had any experience with them, but they've got some pretty pictures ;)

Just use smcFanControl. No extra gadgets, fans, or etc. are needed. Try opening the case, increase the fan speeds to 1500 RPM or so and placing a finger or a hand in the RAM bay area. It gets a very generous air-flow. Adding a secondary fan would not improve things. In fact it might obstruct the flow and actually make it worse.

Excellent advice, thanks Tesselator!

My hottest memory module dropped from 74C to 57C by setting the CPU/Memory fan to 1500rpm.
 
Boy, that is some hot RAM! On my 2008 MP 2.8x8:

4x2GB
2x1GB

RAM fan speed: 900rpm
Ambient temp: 73F

When I'm encoding video or running BOINC, my RAM never goes above 140F (60C)
 
I do use smcfancontrol but like to keep the fans under 1000 if I can. I run boinc when not video editing and have to bump those fans higher but the noise level from the high fans gets annoying. The max upgrade is a bit pricey but since I have an extra hyper x here, I'll experiment with it to see what happens. Tnks for the reply's.
 
But 155 F (68 C) it totally normal at that low fan rate (1K RPM). If you want the temperature lower then pump up the fans. Mine are currently at 1910 RPM and all I'm doing is watching a downloaded TV show in AVI and typing this. My RAM right now is 56 C (133 F).
