Cooling Systems for the Mac Pro??

Dust, airflow, common sense (don't put it in the corner up against a wall for instance), add a VGA fan cooler or copper cooling.... but tells us what card and system you have.

Probably best to start your own thread, can't hurt and better really.

Do you not have air conditioning? If you do consider lowering the ambient temperature of the room. You won't need fan control software because if the computer gets hotter then the fans speed up on their own. All that fan control software does is increase the idle speeds of the fans.

2.66 would be 1st generation Mac Pro with 1333MHz bus.
Do you have 800MHz FBDIMMs?

If you have the Radeon X1900, that is a heat producer, gets dirty, and found in 1st gen.

Copper vga coolers is one step.

Basement or other such below ground - otherwise...

I normally keep my apartment around 75 degrees day and night, so my Mac Pro would get to around 44 C. I installed SMC and set the fans to a minium of 1,000rpm and my system hovers around 30 C. I think the stock cooling setup for the Mac Pro is extremely efficient with adequate space around the system to let it breathe - mine is sitting on top of my desk.

Like I pointed out several hours before your first post, SMC fan control does an excellent job. Give it a try and see if it works for you - it's free and you don't have to install a cooling system. If you're determined on liquid cooling then so be it, you won't be happy with any software fan control solution.

Here's an idea: how about using SMC Fan Control AND placing insulation tubing to direct hot exhaust from your Mac Pro to the outside? That shouldn't cost much at a hardware store.

I've actually had the same problem.

My graphics card shut down quite a few times because of overheating.

Just two days ago, my entire computer shut down and would not reboot. Took it to the store after trying almost everything that would solve a software problem. They told me I probably burnt out my GPU or my motherboard.

So, I started searching for ways to upgrade or improve the cooling and thats how I ended up here.

I suspect that the placement of the computer influences the temperature quite a bit. Any suggestions on where to put my mac?

Hi The hatter,
I wonder if someone, ever replaced fans on a Mac Pro ?
With 3.2GHz processors, using 4 SAS drives (running over 15K rpm), 16GB of RAM...
The cooling configuration is not appropiated !

The two fans on the back side are running out of there normes, and are responsable of high frequency noise.

I use the same Mac Pro configuration, except for the drives, which are 4 velociRaptors, NO noise !

We usely install "NOCTUA" fans on our specific home made computers, Fantastic !
Designed in Austria (Europe)

Nine (9) blade design with 3 adjustable speeds depending on the type of fan.

The NF-P12 (12cm) is surprisingly quiet and is adjustable at 900 rpm : 1100 rpm : 1300 rpm.

I think i will try it to replace all fans !

Any comment will be appreciated.
Regards,
Jean
