eXtreme Power PSU - anyone have one that is NOT Noisy?

Recommended Posts

Hi there,

Based on the Cooler Master name and some reviews, I forked out for an eXtreme Power 600W to replace a blown PSU. Unfortunately, like many others (links below), the fan runs at top speed constantly. I use water cooling and so it's really obvious it's the noise source. I've tested the system with bare components (eg only the motherboard + gfx card powered) and there is no way the RPM of the fun changes at all.

In most of the posts below, people seem to suggest it's a faulty unit, or that the PSU should be exchanged for another model (dodging the issue methinks).

So I'm curious: Does anyone (non-coolermaster employee) have an eXtreme Power series PSU that actually does change it's fan speed based on load, or is this "intelligent fan speed" feature just a bogus sales pitch?

ps: I really can't be bothered with a painful RMA process so I'll probably end up stripping the thing down and mod it to work with an external fan controller. if / when i get to this point, I'll post some JPG.

Sucks when parts make loud noises!! :x

I have gone through so many PCs, and time over time had to fix parts myself... :(

Many, many fans, & not to mention re-soldering back on SMT components the size of dust! :shock:

If you need ( tkl.hui ), I will fix the PSU for you for a very small fee (paypal or money order).

I have my own little PC shop and I have a +record on ebay: "rjf-pc". :)

If not then, buy an Ultra X3 1kW, it's very quiet, affordable, and should do you good. :D

I use an X3 with:

+ EVGA NF68-A1 OC'd FSB

+ QX6850 @3.7

+ 2GB Dominator OC'd

+ 2 8800ULTRAs w/ GPU OC'd, MEM OC'd

+ X-Fi Audio

+ 10,000 RPM 150GB WD Raptor

+ 7,200 RPM 500GB WD Caviar

+ 7,200 RPM 320GB WD Caviar

+ 6 High speed 120mm Case Fans

+ 18w Liquid pump

+ 16 High power LEDs.

I got this Eye-Candy RIG to push out 19,640 :shock: in 3DMark06. :D

The place you bought it, is obligated to respect the warranty conditions, they have to give you a replacement or RMA themself if it is within 1 year. After that you should RMA it yourself.

Also, if you let somebody outside of CM fix it, the warranty will be void.

(PS; check if the fan grill is isn't in reverse...)

thanks for the advice, i reversed the fan grill and the noise went away for an hour, then it came back, but not as loud as before. I was wondering if it is possible to not use the fan grill? if not, im considering getting a new CM rc690 so i can place the psu at the bottom upside down so that the noise doesnt occur.

I have a 550W eXtreme Power PSU and I was constantly experiencing jet-takeoff noise (OK, I know I'm exaggerating but you could hear it clearly 2 rooms away). Today I finally had enough and I decided to take it apart.

To my surprise, the PSU contains a standard 120mm fan which runs at high RPM, which is the source of the near-intolerable noise. I decided to take the chance and replace it with a Cooler Master 120mm silent fan and it worked like a charm.

My only worry is that the new fan won't cool enough and that the PSU will start overheating. To test if everything was going fine I ran Hellgate London for an hour (I have an OCed C2D and a X1950pro) to maximise power consumption and the air that was coming out of the PSU was barely lukewarm and the PSU was only slightly above room temp to the touch.

I only hope it will stay that way as this seems a cheap and permanent solution (it voids the warranty, though).
