Morning! (TYPO IN TOPIC NAME IS BAD, I KNOW. Admins please assist and correct that, thank you :D )

I have akasa powermax 850w, which is a nice psu and have server me for a long time now, however, fan is a bit worn now, my guess anyway, and it has a distinct noise to it now, and i would like to replace it with some better silent fan

Has anyone done this? How hard can it be? I read that older psus required soldering, but pretty sure this one is plug and play. Can you guys suggest a fan? i think its 120mm

Cheers
 
Unscrew it un mount the fan, plug in anuva screw back up, hit the switch and run with a fire extinguisher.

Jokes aside never even been inside a PCU - :)
 
Just an update, dimentions for the fan are: 135x135x25mm. Gonna try and find fan first and then attempt to unscrew the whole thing, already done cable management the other day which took me a while, now i want to cry couse i didnt go for modular PSU :D
 
Very easy to do but just remember the PSU will hold charge for upto 24 hours after its last use! Best off to turn the switch off on the back of the PSU then try to power up the PC this will cause a drain on the Capacitors in the power supply and make it a little safer.

Most modern PSU's use a 2pin fan adapter, so unless you have the tools to change the head on a fan cable I would cut and shut to the one thats already there.

Fans TBH are your choice My preference is Scythe Kaze

Those Dimensions are of a 120mm fan.

Thank you very much, reason i use this foums all the time is someone is always there to help out :D Fan suggested looks like its gonna do the job, hopefully it will fit and i wont need to cut and solder :D
 
I've done the fan swap a few times across several different PSUs.

The last time I did one I put together a quick tutorial..

The biggest issue is finding a suitable 135 fan.

You may be able to mount a smaller 120mm, or slightly larger 140mm fan using 1 or 2 of the existing holes and then use that tape that people use to stick windows on their cases. You might also be able to make new holes in the PSU to fit the different sized fan.

Thank you so much, now hopefully, i wont execute myself with electric discharge :D
 
Pretty sure that no one follows this but if need arises i managed to change the fan without a single hitch
Akasa Viper 1600RPM PWM fan was almost perfect, almost before holes didnt fit 135mm sizing so i had to drill holes manually in the fan :D then i didnt have to cut wires or anything, i just unplugged 2 pin and plugged 4pin that viper had into mobo where cpu fan is, its arctic cooling and has that double fan clip thingy.

All works well, will let you know if anything blows up. Also didnt even electricute myself! YEY!
 
Nicely done. Glad you didnt fry yourself.

Just be aware that the Viper will now be controlled by the motherboard and not the PSU itself. Provided you don't let it go too slow and that it spins up at load you should be alright though. Just don't go loading your GPU/s up without the CPU or the fan will perhaps run too slow for the load.

Just so you know you could have plugged the viper in to the PSU header if there was room.
The red and black wires are enough for voltage control of any fan.
