Corsair CX400w fan swap
Hello,
After listening in a evening to my pc i discoverd my PSU was the source of the noise of my pc.
I was wondering what the best fan is as a replacement fan for my Corsair CX400w.
Scythe Slipstream 1200 or Slipstream 1600.
I probably will use my pc close to max power (Q6600, HD5770 [8600gt gets out soon], few hdd's and a fan controller).
Im thinking to get the 1600 rpm one because SPCR says it runs quiet/inaudible at 7v. The PSU runs the fan mostly on 7v.

The Slipstream uses a plain bearing and doesn't have a very long life mounted in a horizontal position. That's the reason for the S-FLEX F (1600 rpm) being recommended most often for this application. It also has a higher static pressure, which is appropriate for cooling a PS. (If I was going to replace a 120mm PS fan today, I would use a 1800 rpm Gentle Typhoon.)

All PS's have a fan speed control circuit that is usually based on a temperature reading in the PS. The fan will almost never run at full speed unless it is under full rated load and the ambient temperature is high. The S-Flex F in my HX-520 barely spins a a few hundred RPM. The 1800 RPM GT would also be inaudible under all but the highest loads. If you use a fan with too low a maximum speed, it may not be able to properly cool the PS.

Probably. How do you know it will be getting 7v? Are you going to manually set the voltage?! It will probably spin faster than necessary much of the time, when it isn't spinning fast enough the other. It's not like manually setting the speed on a CPU fan where there are sensor reading for the CPU temps. You'll be working blind with a PS.BlackWhizz wrote:
Is a GT 1850 quiet at 7v?

Probably No, but i already put the psu open and have a fan lying on it. My multimeter says on normal uses (gaming a little) the fan runs on 7v.b_rubenstein wrote:Probably.

At 7 volts the Scythe Gentle Typhoon 1850 is spinning about 1100 rpm and is is on the verge of getting noisier. A great fan review is here:

The Scythe Gentle Typhoon has the most non-annoying noise signature that I know of.
