Re: Which 1500W Power Supply is the Quietest?

Water cooling is almost unheard of in the professional arena so this gives you some idea perhaps. Well, "almost" should be the keyword here. I'm in computer graphics and animation, and there are a number of workstation builders that do use sealed water cooling with factory overclocked systems (amon...

Re: Delta PSUs reputation (Antec VP550P)

Thanks for the advice. I had already read the review at Techpowerup, and I also found it was "good for the money". I've ordered two of those Antec and will build two systems around them. I'll check the noise, but it's not critical in this case: they are for the nephews and all they want is higher FP...

Delta PSUs reputation (Antec VP550P)

For a while I've bought just Seasonic made PSUs. They are regarded as "always good", whether they're high or low end. However, for several reasons, I have to consider other manufacturers. I've put my eyes on a PSU with good reviews, the Antec VP550P, which is made by Delta. I have asbolutely no idea...

There's one reason why these coolers are preferable to big heavey towers: transportation. I build workstations for a living and I sell them overclocked with a guarantee.

Re: Antec Kühler H20 620 & 920 CPU Water Coolers

Whether the lab ambient is 10C or 30C does not matter a whit -- it is the temperature rise from the ambient that matters. If a HSF on a particular CPU w/ particular load ends up with a 20C rise at 10C ambient, that is the same temp rise you will see when the ambient is 30C. It does. Air coolers are...

Re: Antec Kühler H2O 620 Water cooler

The pump is irrelevant, as it can be buried in foam and not suffer from it. The fan is what worries me. I'd love to see the cooler tested with a few different fans. I might buy one and test it myself.

Re: Infrared thermometer recommendation

By looking at the specs of various inexpensive IR temperature readers another important factor seems to be the precision or focus of the beam. Some may have a 1:1 relation to distance/area, meaning at 10cm distance the measured area can be as large as a 10cm wide circle. That'd make one such device...

I've stopped the fan cooler with my finger a few times and it's not responsible for the bigger part of the noise.

Ducting the PSU is an interesting idea. I'll see if I can find an easy way to do it (I build MANY workstations so it must be something I can replicate easily).

Thanks for the hint.

What resistor for 9 V?

I use Zalman voltage reductors very often, mostly the 7 V one, but sometimes also the 5 V one. The ZM-RC56 uses a 56 Ohm resistor and gets 7 V to the fan, while its cousin the ZM-RC100 uses a 100 Ohm resistor to provide 5 V. I know somewhere buried in my brain lies the formula that would help me fin...

This is a call for SPCR staff: would you guys be so kind to prepare a PWM fans roundup? Things are pretty well documented here for ordinary fans, but there's little info on the PWM kind. I'm sure many of us would appreciate it if you could add these to your recommended lists.

Thanks!
