Has anyone here used one of Silverstone's fanless power supplies in their HTPCs? I'm looking at this model (st30nf) which seems to get reasonably good reviews. The reason I want this model is obviously because the lack of a fan should mean that it's truly silent and I want the HTPC to run all day, even when not being used. Are there any downsides to this particular model, or has anyone got a recommendation of an equally silent power supply?

Cheers.

I can't see any fanless power supplies, though they do supply "Ultra-quiet" PSUs. Not sure whether Ultra-quiet = silent? My aim for the HTPC is for there to be no noise coming from the unit.

IMHO I would suggest going for very quiet rather then fanless.. at the end of the day PC's generate heat. Your PSU is not just removing it's own heat it is also removing the heat from other components. The PSU and fans that I use (look in my sig) are very very quiet in fact the HDD makes more noise then the fan 90% of the time. The only time I have noticed any noise is when it was a stinking hot day and we watched a couple of blu rays back to back. The video card I have is passive so the case fans have to remove the heat from that.
Even then though it was only after everything else had switched off and the room was quiet.

Thanks for the advice. This Zalman 460W Ultra-quiet PSU looks good: http://www.ascent.co.nz/productspecification.aspx?ItemID=344066

I have had the ST30NF for 3 years in my HTPC. It works great. However my case is designed for it and has a large heatsink that the Power Supply touches. This removes the heat from the case. I have a friend who has one in a normal fan case and it got fairly hot but worked ok.

I have one of these and I dont think i even hear it. The HDD and the CPU cooler make the only noise in my rig - the case fans are virtually silent too.

I have noticed that the cheap PSUs available these days seem to be pretty quiet too..

EDIT: i bough my zalman kit (i have the HD160 case too, which is an excellent case) from these guys: http://www.quietpc.com/

It will be interesting to see how good it actually is, but I'm just about to build with Corsair VX450W PSU. It is very efficient (=less heat), and has variable speed 120mm fan, so I'm hopeful will be pretty quiet.
This review I found suggests it pretty good

Might know better after the weekend
