Corsair H50 Water Cooling Kit

Lets try again...

Nearly finished me new build..

just gonna try it with the standard fan first..

Running the i7 @ 21 x 170 idle temps about 34-37, 30 mins of intel burn maximum saw highs of 62ish

Need to get in the bios and do some serious clocking, and maybe change the TIM to MX 2..
 
Finally managed to install it (sort of). The things you put into the backplate are badly threaded. So when I turn the screws they turn too and the screw doesn't actually tighten.

Meh, 3 screwed fine and ones loose. Temps seem ok so I'm not too bothered.

Adding another fan for push/pull adds to my temps!
 
Here's a few pics of mine. Will be swapping the Akasa for a Scythe Kaze Jyuni 1900RPM next week and maybe suspending the antec.

Why do different fan speeds matter than much when using push pull? Surely as long as air is kicking out faster than being pulled through the radiator

My temperatures dropped several degrees when I added an Antec Tri-cool to my H50 in push-pull. It will increase static pressure - which will increase CFM through the rad. In push-pull without a rad between, i.e. very low resistance, chances are doing so would indeed decrease airflow, but not so with a rad in between :)
Click to expand...

It seems to me that as long as the fans are somewhat similar, then you should see gains. For example, if the exhaust fan is less effective than the intake fan, there might be an *imperceptible* increase in air pressure between the two. However, we're not pushing water or oil through these impellers, so even a 20cmH20 increase in air pressure isn't going to burst the solid radiator mechanism.

in fact, as the 'compressed' air in the radiator expands, one might see a phenomenon called adiabatics, whereby the gas expansion actually causes cooling itself [hence the reason spraycans get a cool nozzle when in constant use]..

Matched fans sounds impressive, but I'm not worried about slight tolerances.
 
I have, however, found that an Antec Sonata Elite case won't hold an H50, because the pop-riveted PSU support bar fouls the side of the radiator mechanism. Interested to see what cases you're using to fit this.

Anyone with a near-silent case solution, with good airflow for RAM and motherboard, which fits an H50 well?
 
^ I would have thought as long as the exhaust is the same or faster RPM/air pressure than the fan pulling into the radiator, all will be good. If I have a 3000RPM fan, sucking in air but only 200RPM exhausting it, then I imagine it would build up heat fast as it cant get rid of it fast enough. Especially as its from inside the case where the graphics card, north bridge etc sit close by

I agree that hopelessly mismatched fans will be detrimental to performance, but most 120mm fans seem reasonably well matched, especially those for sale on OCUK.
 
It's common knowledge that push pull fans should be evenly matched. However I cannot think of any reason why this should be so.

One fan is taking air from an approximately static reservoir and trying to force it through a considerable resistance. The other is accepting moving air, the amount of which depends on the performance of the first, and exhausting it against zero back pressure. The two fans are operating under completely different conditions, so it seems slightly ridiculous to think that matching them exactly will be the optimum arrangement.

Reason for questioning this common knowledge is this datasheet for a counterrotating fan. The intake blades spin at 6200rpm, the secondary stage at 3800. This is without resistance between the blades and not particularly comparable, but it makes sense that the second fan should be spinning more slowly as the denisty of air moving through it less.

(constant mass flow rate through the system, passing through first fan accelerates the air so decreases density, so the moving air reaching the second fan is at lower density than atmospheric, so the force required to accelerate it further is less, so it should spin more slowly.. I think).

Some testing on this here.

Intuitively I would have thought the first fan encounters more resistance so spins more slowly, 'getting it up to speed', then the second fan would spin faster, accelerating the air from the first fan further. And that accelerated air is higher pressure, because (obviously) there is higher pressure on the outlet of a fan than the inlet, hence the static pressure rating fans have - and higher pressure would mean higher density.
But I've not read into it at all. :p
 
I found that putting a Scythe 1900RPM fan blowing into the radiator from the inside then the Noctua on behind the radiator exhausting, gives about 51c load. This is compaired to 63c load when the 2 fans are the other way around.

However im not going to use the 1900rpm fan, i cant be bothered messing around lowering the speed of it. I used both on the CPU header
 
I have just finished putting my new Core i7 rig together. Should I be able to hear the buzz of the pump once the case has its sides on?
 
you shouldnt really be able to hear it with the sides on, i would give it a week if possible see if it settles down - this seems to happen quite often. if its still an issue get it replaced.

also check the rpm, i found mine made noises when it WASNT at full speed. (1400rpm)
 
Here it is:

My new build with the H50 installed in an Antec P183 case. Just powered up for the first time, the pump makes a burbling noise every so often, hopefully it will go when it has been run in. The rig will be operational at the weekend and I will post an update.
