You might be able to just replace the fan with a higher quality one. I've replaced a desktop power supply fan before that had froze up. If you have the same NVR as I have it looks like a standard size fan. I'd have to look again to be sure. The fan was hard wired to the power supply instead of a plug so you might have to do some surgery.
Not really sure where you could buy one. And if you did it might still have a crappy fan ...Thanks for the info.
Could i just buy a brand new power supply? not just the fan inside the power supply?
Did you put in a different fan...?I took power supply apart, and took fan out, the fan noise alone makes noise of over 45dba. Qsee should really be ashamed of themselves of approving such a loud power supply.
The Costco system I bought had 4MP cams and a few reasons why I wouldn't send it back...I'm seriously considering returning my QC8816 from Costco at $1299 + tax for this unit.
Newegg has no tax.

Any reason why I shouldn't?
Cons: Only downside I can see if 3MP, field of view is slightly more narrow, and a max of 8 cameras, can't output to a siren, ext. motion sensor.
Pros: Quite, Save Money.
Update on fan noise.....
Had to replace the power supply fan this week on our Q-See 8816 NVR. It was starting to make noise as the cheap bushings were wearing out.
It's 60mm x60mm and 10mm thick. 12V / .3 A
I replaced it with a 60mm x 60mm 15mm thick fan. Rated at 12V / .12 A
It's a little thicker but fits snug.
Quieter than a desktop PC.
It's a little tricky taking the power supply apart. Test the wire connections first before you solder them.
If you can't find a compatible fan just pull the old one out and connect a fan on the outside of the power supply box and use power from the HD cable.
I also have another external power supply fan pushing air in and powered from an extra HD cable.
I got the fan at Frys Electronics but there is no link to that fan online. As your power supply is different you would still need to take the fan out and check it's specs like xgsound mentioned. Make sure the fan is pushing air out when you hook it up...Do you have a link to the power supply fan you used for the replacement?
