Finding Specs on Stock Fans

post #1 of 6
Thread Starter 
Anyone know a good site where I can find the performance specs on some fans that came with my PC? (Nidec B35502-35) It has those PITA proprietary 5-pin/4-wire dell connectors on them and I'm wondering if it's changing the connectors on them and continue using them, or if there are fans out there that would provide better performance and more quiet. Any input would be greatly appreciated.

Fan Specs:
Quote:
P/N: TA 450DC B35502-35
. Size: 120mm x 120mm x 38mm
. Type: PWM (Pulse Width Modulation)
. Rated Voltage: 12V
. Operating Voltage: 4.0~13.40 VDC
. Input Current: 1.40A
. Speed: 3600 RPM
. Air Flow: 130 CFM
. Noise Level: 50 dBA
. Bearing System: Dual Ball Bearing

You can change them to use standard fans but you will need to re-wire the connector.

Thanks for the info. Much appreciated. Since they are PWM fans that makes it tough to use the specs to determine if I'm better off getting different fans. Thanks again.

Other than the dB rating, the Nidec is very good. I would definitely use it!

Nidec fans are awesome sink fans coz of their massive amount of static pressure. They are however very loud at full voltage/power, but move alot of air and cool very well. if you have PWM, definately use it if you dont wanna listen to their loudness.

Hey pyro,

It's good to hear that Nidec fans actually have a decent reputation. I sort of assumed that since they were stock fans from a Dell (XPS 730x) that they might be crummy. Anyway, the thing is, these fans (3 of them) are not being used for heatsinks; they are just the case fans. If I understand what I've been reading in these forums correctly, case fans really don't need to have static pressure, right?

The reason I'm asking is because I upgraded my motherboard from the Dell board and now only have one PWM available on the motherboard (for the CPU fan). Since I'm not really taking advantage of the other PWM fans now (I think it defaults to 30%), I was trying to see if there were better or more appropriate case fans that I could use. Ideally, more airflow with less noise. So, since these Dell fans are PWM, it makes it hard to use the specs to find a non-pwm fan that would be comparable or an improvement.

Knowing that these Nidec fans are actually pretty decent makes me not want to modify them unless I have to. Oddly enough, unlike other Dell fans I've seen posted on the forum, all the wires connecting to my dell fans are black.

Hope I made sense. Thanks.
