Would these actually work?

I was just on electroseller.com and found these (http://www.electroseller.com/Merchant2/merchant.mvc?Screen=CTGY&Category_Code=fanscpugrs) 1U HSF's. Would these actaully keep a CPU cool? It looks like they'd be handy in a briefcase mod or NES computer or similar. I just wonder if they work ok.

they work, but not so well, plus they are really loud.

Like >70db

Yes they would work... They are used in servers.

U is a form factor measuring 1.75 in.

[stan03]

whoa in servers so they can handle alot of heat then?

[I.M.O.G.]

Well, they can handle cooling a single processor.

Keep in mind that a heatsink like this would be used in a server rack... A standard server rack is 73.5 in high, or 42U.

If each layer was only 1U high then that would mean there could be 42 servers in a single rack = one hell of a furnace.

Rooms housing such a server would be airconditioned well.

Not really, they aren't meant for overclocking, and have very little surface area.

1U servers are VERY small.

could they be used to heat the building in the winter also?:D

1U servers are not necessarily 'small'... they are just thin =p. I put up a couple mac servers that were probably 80lbs each. That's small, but... I'm repeating myself.

Anyway... yeah. Those heatsinks also depend on a *lot* of airflow to cool the 1U servers. Most 1U servers have very intelligently designed airflow... they can get by with having such small cooling.

Thanks everybody. I don't want use one in my own system but I was wondering how well they worked incase I built a really small system.

Now I know I can build a small system, but it has to have good airflow and that can be hard.
