Just wondering. Got a unibody i7 Server and Handbrake and even iMovie cranks the temps up big time. Anyone got a way to set up external fans to cool this better? I had it on its side now with an USB fan blowing on the bottom but temps still go to 98C using Handbrake!

What size fan do you have below?

You might try something like the Cooler Master NotePal X3 or NotePal X-Slim. They are made for laptops, but push a lot of air with their larger 160mm and 200mm fans. The base of the NotePal X-Slim seems just about perfect for the Mac mini. At $20 on Newegg it might be worth a try.

I'm using a 120mm external cage fan that throws out 66CFM.. don't really know if it's doing anything tho.. think of trying to use it as an exhaust may be better..

I use a similar one from Cooler Master with my 2011 Macbook Pro. It does a tremendous job with heat dissipation. Especially while running Handbrake or watching HD Flash video. Perhaps as much as a 10 degree difference.

Are you using handbrake to rip a DVD? If you are I'd suggest getting MDRP (mac dvd ripper pro) and use it to rip the .dvdmedia to your HD then use handbrake to transcode that way the time running the DVD is limited to a quick rip and the time processing the file isn't also running the DVD. Transcoding the file can take an hour or two, if the DVD is spinning that whole time it can heat things up.

i'm considering a 'cluster' of mac minis (4) - do i need to worry about cooling? they don't seem to get very hot but reading these forums i'm worried... should i be thinking of something like this?

what considerations should I make if I stack them??

Keep your A/C on all day and the problem will be gone.

Which means nothing if you don't tell us what you are doing with that cluster.

Of course you need to worry about cooling when you implement a machine in a way not originally intended. That would be very ugly without the associated 19" rack! The general idea isn't too bad though, that is keep the Minis spaced out for cooling.

Don't!

Seriously the newest Minis have air intakes on the bottom, you don't want to restrict that or bias the air with heat from the underlying unit. If you want a vertical solution, space will have to be provided to maintain normal air flows. Even then heat rises which may mean supplemental cooling.

By the way, alternative ideas:
1. http://sonnettech.com/product/rackmacmini.html
2. http://www.h-sq.com/products/minirack/

Not that I've had experience with either solution above. In fact my engineering mind says cooling will be a problem. However they are legitimate ideas for you to consider.

I have a 2102 (current) 2.3 GHz Core i7 Mini and it runs full throttle 24/7. Yet it does not get excessively warm because:

1. I regularly clean the dust out of the heat vent.
2. There are no obstructions to the sides or to the top of the machine.
3. 99% of the time, the machine runs headless with no monitor attached.
