How should I orient my AC64 Freezer Pro?

[Comdrpopnfresh]

I have a rosewill 600w psu with a 120mm exhaust fan. I always keep it on low (I find it too loud on high). My case also has a 120mm antec tri-cool fan as a direct exhaust (I also keep this on low). My question is w/ a x2 3800+ with an AC64 freezer pro, should I direct the fan to blow towards the rear, or upwards?

I have an Asus a8n32-sli deluxe mobo. So I was thinking I might be able to reduce my temperatures overall by putting the supplied heatpipe fan on the heatpipe, exhaust that heat out through the rear 120, then exhaust the freezer pro through the PSU.

will exhausting already hot air from the cpu through the psu decrease the psu's life (but then again, if cooling the heatpipe cools the ambient temperature, this solution may put less heat through the psu than leaving it to suck out case air)?

I'm concerned because I recently removed the heatpipe form the mobo and put as5 on each of the three collectors. now it's too hot to touch on the three collectors (I'm assuming this increase in temperature on the pipe means less on the actual chips it covers?).

I also have a 120mm fan helping to pull air, blowing from my hdd trays to the expansion slots. I have a gig of crucial ballistix ddr400 which gets hot to the touch (this is situated right in front of the freezer's fan, on the intake side...

Do what you want! IMHO, it doesn't make any difference...

I'm running two Tuniq Tower 120s and a Scythe Mine 3, and NONE of them feel warm to the touch -- ever -- no matter what!

Personally, I don't think HSFs put out enough heat to worry about... 😉

Rear. A lot of air from the Freezer actually goes upwards even when the fan is blowing towards the rear.

so then wouldn't it make sense to aid in that air going upwards? I don't know if my arctic silver has set, and even if it has, I have a bunch left, so I might just give it a try, wait a bit for it to set, then post some results...

You want it going from right to left(to the rear) which should be into a rear fan. This gives great airflow and should lower mobo temps and cpu temps.

Um...

What do you guys mean "rear"? Hello?!?!?!

Exhaust fans and PSUs both blow out the rear, yes? 😀

Like I said, it doesn't make any difference...

PSU fans are typically slower moving than exhaust fans, right? And the PSU is already hot as it is....so why dump more hot air into the PSU when you can exhaust it out the back of the case?

Sigh...

Once again, it doesn't make any difference!

CPUs don't put out THAT much heat and it exits "out the back of the case" either way...

I actually turned the Tuniq around in this machine to cool the ramsinks on my video card and NB. Works great! 😀

You want the air to flow from the front right out the rear exhaust.

another vote for blowing air towards to rear exhaust fan

the temperatures were horrible! I think it's because the ram and everything else just poured heat into the case, and the hsf kept the exhaust fan from moving much out, and the fan on the PSU was too slow. However, I spent about 20 minutes applying thermal paste, and got it so thin the writing on the ihs was still discernible. When I took off the hsf to position it towards the rear again, the paste in the center (right over the actual processor cores I believe) was untouched. turns both my ihs and hsf are concave. so at least this experience led me to figure out that I really need to lap both of them.
