Alright, I just took my 400w Powmax, took out the two fans running at 7v @ about 25cfm, and replaced them with one fan at 12v @ about 80cfm. I dont have it blowing directly onto the heatsink, its sucking the air around it and out the back.

;;; = heatsink
X = fan
> = airflow


> ;;; > X >


Will this method keep the sink hotter than normal? Im really tired right now, but I feel there is a 99% chance it wont effect it.

I wired it up to 12v by scraping some of the plastic from one Yellow wire then soldering a wire to the fan to the open spot. A wire to ground. ETC. This wont effect anything right? Its just like if I had plugged the fan in, correct?

Lastly, being shocked by wall outlets, psus, and open wires suck. Ive been shocked three times over the last two weeks while doing different electrical mods to stuff, hehe, my chest hurts!

Thanks alot, any feedback would be greatly appriciated.


... = fan
 
To me that seems to be an upgrade in cooling so I say it would be fine. Why did you swap the fans out for a louder one?
 
I had too, my PSU has a fan that was outside the casing of the psu. Due to my most recent mod, it was a huge hassle to have that fan in the middle of everything. I modded my PSU into my drive bays. I had a crappy worklog that nobody replied to at all and didnt comment on, but Im going to post super detailed pics of all the stuff Ive done to my computer in the last week when I take it apart to paint it.
 
In this order

outside of case > fan > heatsink >air flow holes to inside case

I dont liek single fan designs, personally. why not add in a nearly silent fan to suck air in the psu and then have the 80mm blowing out? or vice versa.

If I want a fan to blow directly onto the heatsink, and the air not sucked around it from behind, then I would have to put a fan on the outside. I might try to find a thin fan, but I dont know if they exist.
 
Any more feedback on this? I want to make sure before I finish doing other stuff to my computer and start running this psu 24/7. Thanks alot.
