Quiet cooling

[timmillwood]

I have recently moved house and have a nice new office for my computers, but my PC is pretty loud and making the room hot.

I have the Antec 100 case with the two fans that come with it, also a front fan, CPU fan, Graphics fan and PSU fan.

I think I need to get rid of a few of those but also increase the effective cooling.

The loudest seems to be the PSU.

Only ways to stop PC from heating up room are turn it off or duct the heat out of room.

What are the specs on all your present fans / components?
With the 2 supplied exhaust fans trying to pull air through case and only one intake they will be much noisier.

You need to add another fan in front. Easiest way to quiet case fans is to temperature control all case fans. Unless you are using 50% or more CPU they will run slow and therefore quiet. I have a Define R2 so similar case with additional 140mm intake in bottom running 4 case fans; 3x 120mm and 1x 140mm. All PWM controlled by mobo CPU fan socket with Akasa PWM splitter which uses PSU molex to power fans and mobo to control PWM signal.

What PSU do you have?

No idea how much clearance you have under case for PSU fan to draw air but you need a minimum of 40mm. More is better. A fan needs it's blade length in minimum clearance from intake surface. If you don't have the clearance the fan is trying to suck air harder then it should and therefore makes more noise.

You could change all your fans to low rpm fans (my two Gelid Silent 12's are pretty quiet), as for noise from a power supply the fan can also be replaced in that, but at the cost of voiding warranty. Graphics card fan profiles can be set up in MSI afterburner I think, and you can reduce the speed at which the fan spins at higher temp levels if you prefer the quietness of a system over optimal cooling.
