Watercooling 3 way sli GTX 280 + i7

post #1 of 17
Thread Starter 
So I've been putting this of for two years now but now its time to do this.

My current setup that runs too hot is three GTX 280's and an i7 that I'm planning to cool with watercooling. I was planning to order it all from EK waterblocks due to them being on the same continent as me and they seem to have a good reputation.

Now I was wondering, what will I need? The EK support guy was not too helpful so I'll do my research here.

From what I've gathered so far I need a 12v pump, some kind of reservoire, and probably more than one radiator. I was hoping to get away with a 240 and 360 as I've seen them modded into a thermaltake spedo which I have.

Will I be fine with those rads or do I need to go even bigger?

Also is it important to have a large reservoir?

These are the questions that I've yet to find answers for after searching the forums for a few hours.

I'll be grateful for any help received.

Most people would say that a 240 + 360 would do fine, and I'm inclined to agree.

As for pumps and reservoirs, I would go for MCP355 + XSPC res top. You can also go for EK's multioption reservoirs and use a MCP355/655 with a EK x-top. 2nd option would cost more, but imho makes your case's interior look nicer since EK's reservoirs are easy to mount to the sides of your case.

EDIT:
Imho the size of reservoirs does not matter, but I tend to prefer larger reservoirs for aesthetic purposes

The 355 is the loudest pump out, I'd get the 655 in XSPC Res/Pump housing, other then that, everything snips said is bang on.

355 is loud? Then is it normal that my GT 1850s are actually louder than my 355?

They're both under 30dB, but the difference is the perceivable volume of each. A fan has a lower perceivable volume due to the type of sound it makes. A 355 has a higher pitch sound, so it's easier for the human ear to hear. I have a few 355s and a few 655s. The 655s are completely silent, while the 355s are distinctly heard. I wouldn't say the 355 is the loudest pump, but it's much louder than a completely silent 655.

Thanks for the fast replies I'll look into the different tops. I might as well go for the 655 while I'm at it. Is there any functional difference in going for a pump reservoir combo or having them separate?

a pump res combo would perform better than just a normal pump in restrictive loops

Oh, really?

Well, comparative to other pumps it is pretty loud, I might be thinking of the 35X or something.

Eh, I'm getting the 655-B with XSPC res/pump combo and apparently it's very quiet.

If you do get the 355 apparently after market tops increase performance.

The functional differences are two fold. Pump/res combos act like having an aftermarket top, increasing the pump's performance (not as much as a separate pump top would, but better than stock). The second difference is more aesthetics. You use less tubing and have less clutter since the pump and res are combined in to one unit.
