Hi, Reader

I have a Rosewill Stallion 500 watt power supply that is quite noisy till I noticed now. I just noticed this because I built a computer for a friend and their power supply was a Corsair CX430, the computer made no noise! I always have headphones in, but when browsing the internet it is quite bad. Taking the drastic measure of replacing the entire fan seems a bit much for me, I have a couple of 120mm fans but the work seems a bit risky for the reward, I've never oiled a fan before but from what I've read it seems to do miracles for some. Anyway to fix this noisy power supply?

Actually, the intake on you PSU was supposed to be facing the bottom vent from the start. Installing it the other way means you were drawing hot air into the PSU which would not help to keep it cool like the cold air from the bottom and likely affected it's performance. Glad to hear the main issue was just a faulty fan though. If you really want to quiet things down while improving cooling performance at the same time, you might consider replacing some or all of the case fans with Noctua or Noiseblocker PWM fans. They're much quieter than any of the Corsair fans and most other fans on the market, especially no-name "cool and quiet" ones.

NO. And the Stallion series are cheap Tier 4 PSUs. When the bearing starts making noise, it's time for a new one regardless of brand or model. You're likely to cause a much larger problem if you attempt to introduce a flammable liquid into any area of the computer, especially the PSU. If the PSU is still under warranty, RMA it. If not, get a good one. That unit was terrible even when it was new, you just didn't know it. The CX is better but still not good. You want something made by Seasonic, XFX, Antec, Rosewill's Capstone series, most EVGA models or even a decent Corsair would be a much better choice than that Stallion.


Anything on the Tier list at Tier 3 is ok, but Tier 2B or higher is very much recommended.

I will call Newegg later today to see what I can get in terms of repair. The noise wasn't bad when I first got it, my guess it just starting get worse as the days went by. If they don't accept it, or my warranty is out, then I will save for a better power supply. I've been looking at a Corsair HX650. The Rosewill Stallion power supply, the RD500-S2B, has ridiculously short cables for any cable management. Oh well, you get what you get in a Newegg bundle.

Absolutely true. I'd never purchase a bundle that comes with a PSU from Newegg or TigerDirect. TigerDirect uses the Thermaltake TR2 in most their bundles and Newegg uses the Stallion a lot in them. Both are piss poor.

Rather than looking at the Corsair, which is overpriced, I'd consider this EVGA PSU. It's one of the best units made by anybody currently making PSUs and is much cheaper.

Thank you for all who have read this thread. I have found my problem why my computer has been very loud. My H55 Corsair CPU Cooler had been in my computer for over 9 months and the bearing in the fan that came with is must be bad, cause at 300 RPM the thing was screaming. I have extra fans from Fry's that are "Cool n' Quiet" and they work perfectly fine. I also worked on the power supply and did some extra cable management, I flipped the power supply upside down, there is a spot for the fan on my case for the fan to be upside down, and it is as advertised, "Whisper Quiet".

Conclusion: Bad Corsair fan
