post #1 of 15
Thread Starter 
Hey

My fan is spinning up like crazy and ive been reading about changing fans.

The fan on the psu is a 2 pin connector. The new fan has 3 pins.. wich of the wires do i use? iknow the black is ground.

Or can i just plug the new fan in the motherboard and let it controll it ?

First off please use the embed function.

And second its not a very good PSU you have sory.
So replace it its not worth keeping or trying to fix.

64mv of ripple on the 12v rails at a 200 watt load? thats just pathetic
98mv of ripple on the 12v rails at full load which is just 22mv short of ATX specifications.

40mv on the 5v rail is not very good either.

Nope throw it out its not worth keeping.

shilka is a wealth of knowledge when it comes to psu's and much more, you've been provided with some good advice, just saying. with that being said it should be a red and black wire for the power, and yellow on the fan will not be used.

edit: also if you want to plug it into the mobo you can control it that way too

Trying to fix and old PSU that is not very good is a waste of time unless you are totally broke.
Its old its efficiency is not very good and its build quality ripple suppression and voltage regulation are all average or worse.

No its not worth trying to fix and you would be better off getting a new PSU.
Just to compare the EVGA SuperNova G2/P2/T2 and the Corsair RMi/RMx has better ripple suppression at 100% load then your PSU has at 20%

10-15mv at 100% load on the 12v rails vs 64mv on yours at 20% load.
98mv at 100% load is 9-10 times worse the G2/P2/T2 or RMi/RMx.

Edit: last but not least i have no idea who the OEM is but going by what i have seen i think its Enhance Electronics which has a very bumpy track record.

Good advice cannot accurately be described as no help at all. If your PSU fan has already failed, what other parts of that PSU are about to fail. PSUs often take out other PC components when they die. Balance the value of your PC versus the cost savings of not buying a new PSU.

Going by that he has a Mist branded PSU he is either from Norway Sweden or Finland or he bought it from there as Mist is only sold there from what i could dig up.
I know most of whats available in those areas as i am Danish myself and often check out whats available around me.
