Re: Connecting psu fan to motherboard.

I did it. I found an unused Cooler Master case fan 1200rpm at home, so I decided to go on and replace the fan for this PSU. The PSU fan is attached with a small 2-pin conenctor, as expected. I removed it and installed the Cooler Master fan. I had a small problem: I could not re-use the screws that w...

Re: Quiet / Noisy Monitor Survey

Benq VW2245 Very very cheap 21.5' LCD display, Full HD. I have 2 of them, no noise at all. Benq claims that it doesn't use PWM at all, but direct voltage/current regulation to dim the backlight. Tested at 0, 20, 50, 100% brightness settings. No flickering detected. The external AC adapter doesn't bu...

Bitfenix Spectre LED fake Hydro Dynamic Bearing?

According to the website http://www.bitfenix.com/global/en/products/accessories/spectre-led#specs these fans are Hydro Dynamic Bearing. I bought one of these because I knew it would have to operate at fairly high temperature as it's the only exhaust fan of the system (Cooler Master Elite 110 case). ...

Re: It is so hard finding a PSU doesn't have high pitched no

It's the first time I read of someone having my same troubles :D I have very sensitive ears and tend to hear electrical high pitched noise almost everywhere. I can also hear it from notebook chargers (bricks), AC to USB chargers, a USB hub (!). I owned a lot of low to mid end PSUs, maybe we can figu...

Re: Connecting psu fan to motherboard.

I've checked: the fan blades are not touching anything, the noise comes directly from the fan hub.
I'll order the new fan shortly. Maybe first I'm going to run a short test to see if the psu powers up without a fan connected.

Re: Connecting psu fan to motherboard.

PSUs usually have overheat protection, but no fan detection. It's possible to do as you suggest. Other options are to connect the new fan to the PSU fan controller or directly to to the rails. Your way is best if you want to control the fan. Just don't forget to plug it in. :) Thanks for the reply....

Connecting psu fan to motherboard.

I'm going to replace the fan of an Antec Neo Eco 400M with a Akasa Apache. I will connect the fan header to the motherboard and regulate the speed based on system load. Will the psu work as normal even if there isn't anything connected to its internal fan header? Do PSUs have protection systems that...
