Silence PSU fans

[Tenacious]

In my everlasting mission to silence my pc, I would like to have a go at slowing down my PSU fans. The PSU in question is a 600W Magna, not that I think this should matter and should be a generic mod. But I would like some advice on wether it is safe (for the PSU) to slow down the fans, and if its easily done by placing a resister inline?

I know it can also be dangerous working inside a psu, but feel confident enough to accomplish this and the fans can be easily adapted without going near any large caps

any advice, muchly appreciated.

1. i do the same & lost my psu
2. if it's a good one then it has temp ctrl for fan & this = no need for mod
3. be well to do in ur missions...

How much hot air can you feel comming out the back?
If the answer to this questions is fairly hot then I would leave it alone. If you caould somehow measure the temp in there, then how hot is it.

well it does push out hot air, but my ambient temp inside is quite warm. Anarion what model PSU did you damage? was it due to overheating?

Dont slow down the fans, get new more efficient ones. Raising the temperature in the PSU can decrease performance.

push out hot air ----> never ever think about mod ....amb temp is warm ----> DO NOT play with it ...it waz some gold SH psu ...yep totaly for one reason ; OvEr HeAtInG.....1.this days, quality gone 2.normal psu's become hot & sonorous
3.we make mistake think we still live on ol days, make some mod -bang- = &harware went completely haywire...
a good psu is a silent one if not it's no good also a good one is cool if not no good also rock stable if not no good.


hmpf

Replace your PSU fans with more efficient ones (More CFM less dB). There are guides out there for this (though I think you will not need one for some reason ).

A silent pc is good, but its no use if you sacrifice cooling performance for silence. Invest in decent fans, a decent case, a good fan controller or just go down the H2O road!
