I don't recommend getting two 240 radiators unless you really need them, it's just too expensive for the gains. One issue with the various Reserator systems is the combination of aluminium and copper. In a system with both metals an inhibitor becomes necessary. Zalman provides an inhibitor, but if y...

If you have space for one, you may consider getting a triple fan radiator. They tend to be only slightly more expensive than the dual fan radiators, and provide 50% more surface area. More area means lower fan and/or pump speeds.

My D5 in stock config (I bought an aftermarket mod) at about half power was about as loud as an 600RPM - 800RPM S-Flex, but lower, more midrange, with a faint very high pitched hiss. At full power it had a grumbling noise and a lot of vibration, but at half power it wasn't too bad. The aftermarket m...

The real problem with the XSPC kit is the loud pump. You'll have to replace it with a quieter one, and that will make the end cost higher than just buying custom. A D5/MCP655 is about $70 Cad. Primochill tube is about $20 Cad for 10'. An MCR220 radiator costs about $60 to Cad (don't know if it's ava...

I would have thought high-end air-cooling would utterly trounce a thermaltake bigwater - it was worse than top-end air-cooling when it came out, and struggled with 100w processors. A 300w graphics card would probably turn the water to steam. Ditch it and get proper water cooling or else wait for af...

I too am interested in this, as I am looking at the XSPC X2O 750 Dual Complete WaterCooling Kit which includes the pump/reservoir. I would have to mount the pump/reservoir somewhere other than a 5.25" drive bay though as all of mine are full (Optical Drive, Kaze Server fan controller, 2 x Scythe Qu...

If you have a corrosion inhibitor you can mix copper and aluminum, but I don't know how well it would work or for how long. It would likely be easier to get a standalone radiator. It would also be easier to get a copper/brass radiator than it would be to find an aluminum water block, but if you have...

The Liang DDC/Swiftech MCP350 is reported to by a pretty quiet pump. I haven't heard one myself, though it's supposed to be quieter than a D5/MCP655. Swiftech reports it to be ~25dBa @ 12v, and it can be undervolted to 8 or 9v. Your radiator isn't really a good choice for low fan speed operation, to...

It was aimed at ces, he asked if any radiators were designed for low restriction air flow a number of posts back. Ah sorry. In that case, yes, I completely agree with your post. RPM and dBa aren't really the deciding factors here. Noise character is. A smooth noise character lets the fan spin faste...

The Thermochill PA120.3 series and PA140.3 series are designed for low pressure fans. They have about 10 fins per inch. The Black Ice 480GTX has about 19 double stacked fins, and the Feser Monsta 120.3 has about 12 per inch. There's pic in this link: http://martin.skinneelabs.com/HWlabs480GTX-Revie...

The main problem with Frostytech's temps is the lack of a universal reference fan. If he runs the system with whatever was in the box than you know the out-of-the-box performance. OOTB ability doesn't really matter compared to the ability with the Nexus 120. And from what I gather from random commen...

ProCooling has an active extreme cooling community. Peltiers are rarely if ever used for silencing, as they use CPU levels of electricity to work. They are also very inefficient and get worse as the temperature differential increases and need an independent PSU most of the time. I assume that some ...

1. Yes, the heat must be transfered to the air, but a radiator has more surface area than a heatsink. Ex. I have two heatsinks, both are 120mm square, made of aluminium with an equal number of fins that are equally thick, however one is 1" thick, the other is 4" thick. The 4" one can dissipate the ...

All I see there is someone who didn't do enough research and bought something that would not do a good job. Any forum with a serious watercooling board will tell you that, with very few exceptions, you should never buy a watercooling kit. Swiftech kits are better than most, but there radiators aren'...

Ek Water Blocks EK-D5 X-TOP Version 2 Custom Pump Top for D5 & MCP655 So I bought one of these, mostly for the cleaner shape over the normal MCP655. I didn't expect it to, but it made my pump quieter. With the stock top the pump seemed unbalanced, and had a lot of vibration, with a combination of me...

More heat --> more dissipation applies to both air and water cooling. Every watt used must go out to the air. Watercooling simply has an intermediate heat absorber, the water, and greater dissipating area. You state that temperatures are not useful, than what is a useful metric for watercooling perf...

The basic WC points are: 1. Radiating area can be almost unlimited 2. The Radiator itself can be placed outside of the case 3. Fans work in parallel, lowering speed and noise 4. Replaces loud GPU fans Those are the main advantages of watercooling. Watercooling systems work somewhat similarly to a hu...

The fans on a water cooling setup could be made quieter with lower voltage and different fans, but the pump on a water cooling setup is over 30db, which bothers me since I want my setup to be quiet and cool. Are there methods anyone recommends to muffle the sound of the pump--throwing an old winter...

I have said this before but sometimes it has to be said again. Temps are meaningless, it is all about heat capacity and total heat removal ability. Temps are not meaningless, the simply need to be taken in context. Knowing temps + watts shows heat removal. We were talking about temps in relation to...

Note Since you made two posts with pretty much the same content I'm going to quote my message and your reply. According to this computer power scale, SPCR's test CPU draws about 152w (stated in the SPCR test bed article to be 160w, so I'll use that) at 100% load when overclocked and overvolted. It's...

Here is a Swiftech pdf which states that the pump can be started at 9 volts and run at 8v. That should allow you to reduce the speed, but the 3 pin connector is for speed monitoring. The four pin molex connector is for power. The MCP355 is supposed to be pretty loud, the MCP350 is a quieter model. ...

It's also stated that the temps are from the hottest CPU core, not the sensor labeled 'CPU'. At about 19dBA the No...

I realize what the OP is saying, I just wanted to clarify it a bit for him. My point being that the dead spots, even when the are an issue, are not a large issue. I don't agree that the setup has very good potential. It does have some ability, but the combination of all of the exhaust heat being pul...

Pretty sweet, I especially like the wood box/stand. Very classy looking. Does the rad have any fans or is it fanless?

My only complaint is that it's apparently an aluminium radiator. I personally prefer copper/brass because of galvanic corosion, but you've probably added an inhibitor for that.

My MCP655 is unacceptably loud at full power, but at significantly reduced speed it is much better. The Swiftech H2O-220 Apex Ultima uses the MCP655-B version though. It has no speed control. Also, a Thermochill PA120.2 or 120.3 is a better choice of radiator for sure. A MCP655 at full power is loud...

No problem. Come back if you have more questions.

I wouldn't recommend WCing the mosfets and chipset. Typically they are adequately cooled by their default heatsinks, and even with overclocking they don't get any substantial benefit. That money would be better spent on a better GPU, CPU, PSU, more memory, ect. Even if you watercool everything in th...

If you want to maximize pressure use two pumps in parallel. If you want more pressure, putting the pumps in series would be better. Both parallel and series increase effective pressure, but you are correct, series potentially produces higher pressures. It really depends on the system's restrictiven...
