which way to point my fan on my alpha, blow on or suck off?

[gplracer]

Should the cpu fan on my alpha blow on the heatsink or pull air off?

Blow on!

I personally would say suck off. Think about it. Would you want all that hot air from your video cards and other pci cards blowing on your processor. Didn't think so.

Tested both suck off and blow on with my FOP32, blow on tends to lower the temperature by 3-4 Celcius over sucking air out from the heatsink.

Well then you are just sucking in the heat of them anyway. By blowing into the heatsink you will move more air across the heatsink. What cools your body surface tempature more, a fan blowing on you or a fan sucking air from you? If you have good air flow into the case you should not have to worry about a video cards heating the air inside the case.

Pulling the air or "sucking off" as stated... seems to be a better choice mainly because if you are drawing the air in you are also helping the chipset heatsink instead of blowing the warm air off the sink onto the chipset heatsink (in effect not cooling the chipset). Also if you were to duct the warm air off the heatsink via a ductwork tube to the outside of the case then you would not get the warm air in the case... Also an additional fan helping to pull the air through the ductwork to the outside would help cool even more...


Hummm kinda makes the idea of a peltier a little more interesting (with an Alpha PAL35T & socket 370 board)

Wow, we could turn this into the next biggest debate. I wonder how long this will go on?

If you are from Flori Duh, please don't bother voting on this subject. It would just mess it all up.

AhaHAHa...nice one.

we should get a hardware site (perhaps anandtech) to do a review which solves this debate. i'd be interested in reading it; i'm sure others would be too.

hey guys

sorry..this doesnt deal with alpha..but um my perference is to suck off hot ait then blowing it up on the hs anyways...

but um
will copper spacers?
lower temp ? more?
or will it create more heat?

Mikelou26: No copper shims/spacers will NOT lower the temperature of the CPU. The spacer is there to keep the heatsink firmly flush against the core, eliminating any chance of the heatsink "seesawing" on the core that occurs without any spacers. Since 100% of the heat emits from the CORE only, the copper shim wouldn't have any affect on the temperature.

Read this link here: TBird & Cu shim & alpha (thermal paste between the shim???

The FAN should be "sucking" air away from the heatsink. Infact, Alpha has fan mounting directions on the instruction sheet that comes with the heatsink which directs the fan to be mounted in a "sucking" fashion.
