3m fluorinert FC-77 has been around for ages and is considered the ultimate in immersion cooling, used in the Cray supercomputers of the past. An affordable solution would be nice as FC-77 is stratospherically expensive, but basically perfect.

The 16 blade aerocool turbine creates nice static pressure, works well with pwm, but is fairly low flow.

Being a log scale, adding 20dB to 40dB would make no measurable difference; 1000+10 = 1010.

Normal Sound Pressure Level gauges only read down to 40dB. Only SPCR have openly said they purchased a professional audio one which reads below this. Does this review say anything along those lines? (I can't read French). If the gauge only goes to 40dB and their noise floor is around that, how can w...

Welcome to SPCR! The Nexus is particularly popular here because for virtually all cpus you can adequately cool them with the Ninja at ultra low flows and the Nexus works well over the 5-12V range and has good reliable quiet properties. There's only one theoretical issue - the Nexus is a sleeve bear...

TDP is the thermal dissipation property required of the cooler attached to the CPU. It does not tell you what the amount of heat generated by the CPU is. It tells you the minimum heat dissipating property the CPU manufacturer recommends that your heat sink/fan needs to ensure safe operating. While i...

Actually as a postscript to that previous comment - if you're serious about silencing/quieting, do not pursue lower and lower temperatures. You should pursue lower and lower airflows until you have the lowest airflow that still gives you safe, adequate cooling since any more cooling is just "wasted ...

I my real question is will a Nexus 120 at 12v push more or less air than a Silenx. My problem is that I need air flow and putting in a fan that is quiet but doesn't push enough air kind of pointless. The older Silenx fans with the larger hub put out about the same amount of noise at the same amount...

This cooler is very similar in design to the Thermalright XP120 but comes with a crappy fan and is cheaper.

I'm very happy with my aercool turbines so far (2 of them). They start reliably at 7v and are very quiet at that level. They run fine at 5v as well provided you start them at a higher voltage, but will not start reliably at that level. At 5-7v they are inaudible. The only warning I'd give is the the...

Pccasegear have been an excellent supplier for me. It seems to have been an honest mistake and I wouldn't judge them on that one error.

You can also orientate the Ninja such that the fan is blowing in the direction of the airflow. You can place it with the fan facing in any direction.

I've cooled an 830 and let me tell you it's a formidable task. The stock cooler is inadequate within 20 seconds of full load - absurd. The freezer 7 failed because it doesn't spread the heat fast enough up its heat pipes - despite a claimed TDP up to 200W. There are only about 3 air coolers on the m...

Not really. I get all my information from the SPCR reviews. Read them yourself to see that what I say is not purely my opinion. Furthermore, your motherboard is not listed on Zalman's 7700 motherboard compatibility page so the point is probably moot. Edit: I just checked and they're the same loudnes...

The 7000 provides more than enough cooling for your cpu on the lowest setting and is quieter than the 7700. Why are you even considering the 7700 unless you're planning a fan swap?

The 7000 definitely is compatible (I've used it), but I think the 7700 might not fit and hang over the edge of the motherboard, possibly even intruding on where the PSU is. If you're serious about silencing, though, I dont' recommend the 7000 stock. I have one and it is not quiet enough even at the ...

A good response too. However all I'm after is a factory recommendation for what temperature range the manufacturer considers safe for continued use; ie safe by both your criteria - no melting and no data corruption.

3 Nexus fans would probably provide enough airflow even at 5 or 7V to cool most hardware, and then they'd be basically inaudible. See how low you can drop your flow and still keep good temperatures. I think you'll find the hard drive ends up being your only noise if you do that. The seasonic will be...
