The Test
Right .. right ..  how do you test this bugger ? .. we could do it with a multi-meter but will go with the traditional way .. real-life as that's what you'll be facing also. We attached everything we could to the IDE-RAID test-rig .. 3 HD's, GeForce FX 5800 Ultra, Audigy2, Pentium 2.4 GHz @ 2.8 GHz, DVD-ROM, DVD-RAM, CD ReWriter. Huge active cooling fans and a case with additional lighting.

Then we fired up some games, put in a few CD's, ran the CD's (let them play music), play games and waited to see what happened. Okay, so I played for hours and hours Grand Theft Auto - Vice City ... (really addictive game btw) and of course nothing special happened. We also burned some CD's on the rig as that requires a very stable power supply. Okay you get the idea already .. stable as a house and all that without any additional sound from a fan. Pretty perky stuff.

When we looked at BIOS results we notice that all voltage levels are really stable, only very minor fluctiations could be seen in the order of .1 volts which is perfectly fine. One thing that did worry me a tad was the ambient temperature inside the case. In extreme conditions the PSU will try to dump it's heat through a pipeline construction within the PSU towards the outside. That however is not 100% successful. Quite a lot of residual heat is dumped in the PC case. If the ambient temperature of your case will rise then so will the components inside the PC. So if you overclock a lot then this might get a little tricky for you.

Overall in stressed conditions the ambient temperature of the case will go up towards 45 degrees C which is a tad too much but nothing to really worry about under normal conditions.

Concluding
The proSilence Fanless PSU from SilentMaxx is without a doubt an excellent product. Keep in mind that the ambient temperature of your PC case will rise
with about 10 Degrees C if you don't have any active fans available that get rid of that heat inside. Nothing to worry about, but like I said it might be an issue for hardcore overclockers. For normal usage this product is awesome though. It is extremely stable, we where not able to stress the PSU at all, voltage levels remain very steady and the biggest advantage it's 100% silent. We have been using this PSU for a few weeks now and I decided to move it over into my primary rig which is powered up 24 Hours a day where it's doing such a nice job. My main PC ladies and gentlemen never crashes, I require stability and the proSilence Fanless PSU definitely fits into that package and hey add 0 dB(A) noise level to that. Awesome stuff.

The downside of this product is that it's expensive .. very expensive, 220 EUR. It's like with everything in this business, if you want the best then you gotta pay like the rest. If you are willing to spend a lot of money on it then definitely keep this product in mind. It's really good. Also, please have a look at the SilentMaxx website. They have a lot more silent products that might interest you.

Last but not least, without us asking SilentMaxx also send along a copper heatsink, the SM CoolFlow. Again equipped with a very silent cooling fan, hey .. they have a reputation to uphold. Unfortunately I do not have time to do a review on it as I have way to many product waiting in queue for a review. But people, this is one of the most silent coolers I have ever seen, specifications note 12 dB and hey I believe them. Next to that, it cools so extraordinary well that I decided to make a few pictures and at least note this cooler into the review. If interested go have a browse at their site please.


SM CoolFlow - equipped with a fan for Pentium 4 2.8 Ghz


SM CoolFlow - There's also a faster model for 3 Ghz and above rated PC's
