Shut off fans at night?

post #1 of 21
Thread Starter 
Hey I was wondering if I could shut off the fans on my radiator at night? It would only before like 8 hours then i would turn them back on. Do you think my temps would be bad? Also there is a case fan right under neath it blowing air up and against it. Would that be enough?

48 dba is kinda loud and I want to make it quiet well quieter.

I guess I should mention that I am Folding too, and downloading. So my processor would be under load.

Turn off your fans right now and monitor the temperature for like 5 min. See how far it goes up. if it does not increase too much check it again in 10 min. and again in 20. If it isn't to bad you have answered your own question. If temps rise too much, get those fans back on stat.

Post your results too, it would be good info to have.

Ya the only thing i could suggest is turn the fans off for about 1-2hrs, letting it idle or do w/e its going to do at night, and see how it does. Also it would be smart to set a thermal shutdown temp in bios if you dont already have one set.

Or option 2 would be get a fan controller for the fans on the radiator. Just turn them down to really low at night, and turn them back up as needed.

Otion 3, under volt the fans. i have 2 high flow nidec beta V fans on my rad, both rated at 112cfm and about 48db. I only have them plugged in to the 5v lead and not the 12v lead, so they move im geussing about ~50 and are near silent (~20db? or so)... I have one of those connectors that come with zalman aftermarket VGA coolers works out nicely

Get a fan controller and turn them a low as you have to. Some air is better than no air.

I can't find anything that can handle my fans though, I was looking at the fan controllers, but I don't have an open drive bay, and I can't find a rheostat or a pot that can handle them.

I tried running them in series to drop the voltage down, but they won't even turn on at that voltage, which is like 6V's so 5 volt mod is out.

The only place I know of that has the big rheostat's is Sidewinders, and they are expensive...They have a 25W one to but it's only a $1.00 cheaper..Sidewinder Rheostat - 50 watts

What about Zalman's Rheostats? Also I've heard you can mod light dimmers.

You could just shut down your rig at night, save money, save the environment and save the beavers.
