Is there a Windows utility similar to smcFanControl
Speedfan by Almico offers full fan-control for those mainboard compatible: http://www.almico.com/speedfan.php
It cannot control fans of Macs though. In order to achieve that you have to use SMCfancontrol to set your desired minimum speed and then reboot into bootcamped Windows. The fan-speed setting will stay in SMC memory for as long as you do not turn off the Mac.
I think I may have partially answered my own question, in that it looks like the developers of smcFanControl were working on a Windows version which is still available at http://sourceforge.net/projects/macfan/
I should point out that MacFan 0.65 is no longer being developed.
MacFan requires you to run it from Start > Run... , browsing to the location of the program and then adding the fan speeds in rpm that you desire, as arguments. For example, for my MacBook Pro I enter this statement (including the quotation marks, and yes, I have it located on my desktop for now):
"C:\Documents and Settings\UserName\Desktop\MacFan0_65\MacFan.exe" 4000 4000
which bumps the fan speeds up to 4000 rpm from Apple's default 2000 rpm, just like smcFanControl does over on the Mac side. You don't want to do this following a re-boot from the Mac side, if you've been running smcFanControl, as MacFan is aware of this, and will tell you that improper fan speeds seem to have been saved. Running this following a cold boot results in no problems.
It would be nice if the program's window would stay open after running, to allow examination of all the text, but it disappears as soon as the speed change is complete. It would also be nice if there was a way to store my preferred speeds, so that the computer would start up with these new speeds automatically, without having to run the program. However, it's still an improvement over booting into the Mac OS first to get the fans up to speed, and then rebooting into Windows.
A typical session in Pyramix will get my MBP's GPU up into the high 70s/low 80s (Celsius), but with a 4000 rpm fan on it, it rarely exceeds 65 degrees.
To bring this rocketing back on topic, this is all while running a Fireface 800 as my ASIO interface which, truth be told, also gets a little warm during use.
