Oh wow... very, very easy way to quiet any CWT made Corsair PSU (Voids warranty)

post #1 of 9
Thread Starter 
Unscrew the cover off the PSU (Warranty void, beware) and very, very carefully take it straight off. Note that the fan is on a *very* short 2 pin connector, which barely gives you enough room to take it off clear of the PSU. Now, observe the fan baffle (the clear plastic thing covering half the fan) screwed onto the fan via two screws. Unscrew those two screws and take off the damned thing. Voila! It's now a lot quieter, and I'd think a lot cooler running. When putting the cover back on, make sure that you put it on correctly; the cover should overlap the side guards of the PSU (you'll see) and go inside the bottom guard.

Also, you could take out the fan grille while you're at it. It's removable from the outside, but I'd still do it last.

After doing this, my TX750w is no longer the loud beast it was in my P182. Now, the 4 Antec Tricool's all @ low are what's creating noise. I just need to get my hands on some 800RPM Slipstreams

I know the fan baffle is in the TX750w, as well as in a lot of other CWT made PSU's, so I think they're in other CWT made Corsair PSU's. To check, just look at the bottom of the PSU where the fan is and look for a clear plastic thing blocking airflow.

Oh yeah, and uh... be sure to unplug the PSU when you do this. Wouldn't wanna get zapped.

This has been discussed before. It's there for a reason, directs airflow where it is needed within the PSU.

Yep. Good luck with shortening the life of your PSU.

Is it REALLY that much quieter?

The baffle is there to divert air to the front of the PSU. Positive pressure then forces that hot air out the back honeycomb grill.

You remove the baffle and the air from the fan blows right out the back of the unit.

If you think the Corsair is loud, you'd be better off putting a small resistor on the +12V than doing what you just did.

Does the PSU have some special design in which the fan baffle is integral to normal airflow? Or is it a standard PSU design, and that fan baffles benefit air flow in general for all PSU's that have a bottom 120mm fan and no back 80mm fan for cooling? 'Cause I could live with the latter.

Honestly, it might just be a placebo or awful memory, but now I can barely hear my computer. When I walk into my room, I have to stop and try to hear if it's on. When I wake up in the morning, I'm not sure if my computer's on or off, unlike before.

It's pretty standard design. Most down draft PSU's will have the baffle unless the arrangement of components on the PCB can work with just air shooting straight down and out the back. But in most cases, yeah.. you're going to have a "hot spot" in the front of the PSU where cool air can't get to.

I dont see what the deal is unless your a complete noise freak.
Ive got alot of fans running but the noise doesnt bother me because i know my pc is nice and cool.

Indeed.

Wouldn't it be better to just replace the fan with a quieter 120mm one?
Or is it soldered to the board or something :\\
