Windows 7: Corasir Liquid cooling unit louder and hotter than two fan Noctua

I have never used Real Silent Case Fans but looks like a good fan system if it works well in fireferd's recording studio. As you can see in My Specs I use Noctua fans all over my computer. No fan controller needed just run them 100% off the motherboard or power supply. The CPU pump is hook to the Cpu fan connection on the motherboard and runs at 1450 rpm all the time with no noise. The only thing I have noticed with my H50 is the idle/low load temps are always 23c above ambient (19c +23 = 42c) but under 100% load mid to high 60c is reached O/C to 4.1. Here is a little trick I use. The O.E. case fan on top with push/pull Noctua fans on top blow around and through my DSL modem and router keep them a lot cooler, 2c above ambient. Seem like the router and modem are the only 2 things people never cool.

My case is heavy on fans but the noise is fairly low.
The graphics card gets noticeable under load, but only because I've set it not to get above 65c.
This is amazingly accomplished without ever going above 70% on the fan though.

It is always better to use good quality aftermarket fans with a sealed waterblock

I have the Antec 620 Khuler it was running smooth when first set but temps started flexuating

I dumped the stock fans that Antec gave with the product and bought some mugen sythe slipstream fans my temps have been great ever since

Better off using the quality fans you already have then trusting the package product fans my experience with sealed blocks the fans they provide are not worth putting on IMHO they are just cheap fans with there logo on it that's all

That's not really an opinion, minus noctua I agree completely.
That's pretty much just how it is.
Noctua doesn't make much other than heatsinks and fans though.
Noctua.at - sound-optimised premium components "Designed in Austria"!

For those still looking for quality quiet fans I know the feeling. I like many others I would think did a lot of homework studying a lot of reviews and reading a lot of specs before paying the big bucks for Noctua fans. You can live without them but once you get them you will wonder why you did. The color grow on you in about a year. Because I bought mine through a local dealer I payed premium price of $28.00 apiece. They are worth it to me still today. You can buy them over the net cheaper.

Just for clarification, I have all the fans in my desktop, running at lowest speed (and still runs "cool"). I have the H80 set to lowest speed, and the three case fans in my Corsair Carbide 500R case at low speed (two in front and one on the side). My power supply is an Antec High Current Gamer HCG-620M Modular and it too is a "quiet fan" power supply.

RealTemp GT shows CPU temps mostly around 35C, under heavy recording use they will jump up to around 41C.

With the Noctua's run them wide open with no speed limitation and if possible run them off the PSU and not off the mobo to keep the voltage off the board.

Definately going to get the Noctuas. I have the fans turned down low, and system is still at 30C. And now I hear the Corsair fans rattling. I've never had a Noctua that rattles, so I'll be off the local shop agin in a few mins.

I can connect them to the Lamptron. That has it's own power from the PSU. The fans have a 3 pin connector, and I'd prefer not to be adding redundant molex connectors when I don't need to. The fewer cables the better is my motto.

Prior to upgrading case and cooler my system was at 34C and when encoding media it jumped to 63C. I haven't done any encoding since upgrading, I'll get to that in the next day or two and will revert with temps.

Interestingly, this upgrade was not orginally about cooling. It was that my Antec 900-2 case had too many design flaws that irritated me, most notably the drive cages.

As always I am grateful for all the support and assistance. It is wonderful to be able to come here and get such good advice and feedback. Thank you.

If you are going to be using them for the rad, you may look at the Noctua NF-F12's rather than the NF-P12's. The F12's are 'focused flow fans' and will penetrate the rad better I believe, although the P12's do a good job.

Yes, I have purchased the F12's. Had a look online before I went out. They also have anti vibration pads, and a 200rpm higher max spin (which I hopefully won't need), and they were the same price as the P12's.
