Q: Bumping RPMs question
Hello everyone and happy new year and happy holidays
So yes I am using smcFan i know its not all that good and people don't really recommend it but even so i use it at my own risk.
I just have a question about the fans in my 21.5" iMac the 2010 model to be precise. So constantly monitoring the temperature of my HDD and i reed about the HDD and how that piece of hardware is the most temperature sensitive. So my hdd under load goes up to 45 - 48 that is kinda the max with smcFan on of course.
I usually run smc fan a lot may not be the right word but mostly 70% of the time fans are at a higher RPM than usual.
Now can someone with some knolage please tell me how to set the RPM's for the fans and for how long to run them. If needed i will provide temperatures and other data.
Thank you very much.

I have iStat Menus with the Drive and CPU temps, along with the fan rpms from smcFan, right in the menubar always visible. I use several different settings accordingly. During the winter I generally run at the setting "minimum minus" and, if needed, I turn on a small clip-on fan mounted to the wall behind the computer, aimed at the upper left (as you face the screen) of the back, which is where it gets the hottest. In the summer, I keep that fan running almost all the time. It really helps to dissipate the case heat and keep things cooler inside. But if I'm running that fan a lot, I will dust the back of the computer and the area around the computer frequently. And if it's really hot, as it was last summer with the indoor temp here in the low to mid 90s and high humidity, I just let the computer sleep much more often, or I just shut it down. Like that it's too hot to sit in front of a computer anway.
You really have to experiment with what works best for you. But, to avoid burning up the fan motors, stay in the range of + 200 - 500 rpms. Also den.thed's suggestion to vacuum periodically the lower intakes (along the center bottom and behind the stand) is great advice.
