Hello everyone

I have a quick question as a future watercooling user, i am planning to buy the aforementioned kit to cool my i5 2500 and Radeon 6870. Do you think this will be enough or would i have to additionally buy 120 RAD? I am not planning to overclock the CPU or GPU. I am using the Zalman Plus case fully equipped with fans. I know i should buy another 4 fittings (or so i think) to accomodate the GPU as well (EK VGA Supreme HF) but will the pump be enough for those? What if i have to buy another that additional 120 rad, would i have to upgrade the pump as well? Thanks for any advice!
 
Hey, and welcome to the forum :D

I've been doing a lot of research for my own first foray into water cooling over the past few weeks. 120mm of radiator surface area seems to be the recommended amount per component, so you should be fine even with a slim 240, however, I believe the kits come with a pretty decent radiator, so you'll get that extra surface area from the thickness of it, which should also allow you to run your fans slower if you're water cooling for silence as well as better temperatures.

You will only need to buy an additional two fittings for the GPU block, as two of the four ports will be plugged with stoppers which come with the block. A 240mm radiator will be more than enough for an i5 2500 and 6870 at stock.

As for the pump, any of the popular pumps such as the EK DCP or Laing DDC pumps will be more than powerful enough to get the water around your system, even if you wanted to add another GPU or radiator into the loop. Again, if you're going for silence, avoid mounting the pump to the case, as it will just transfer the vibrations to the case. Apparently thermoplastic elastomer gel is very good for just placing in the bottom of the case and sitting the pump on it, or you can use foam.

Just transferring some of the knowledge I've picked up recently. Hope it helps :p
 
Thank You so much! I am hoping to order the kit tomorrow so will see how it works out :)

I wouldn't buy it if i hadn't made a mistake with GELID Icy Vision which didn't fit that particulart 6870 and i stupidly cut the heatpipes to fit it and got worse temperatures than with stock cooler :) So my next decision was to use watercooling as the current setup is noisy. This time i read lots about but never seen articles on what is enough etc. Thanks again for sharing your knowledge with me.

Just use good old blu-tack. Works as well as elastomer gel and costs £1 (or so)

Not a problem :)

I came across the Gelid cooler when looking into replacing the Twin Frozr II cooler on my 580 because the fan bearings have had it. A lot of people seem to have had problems with compatibility from what I read; things not lining up, it being an awkward fit, etc.

Water cooling is definitely the best option, although it is quite expensive, as I'm finding out... :( :D

Ah, I might give that a go :p
 
Hey, ive got the same kit. Its a quality piece of kit but just make sure you get a EN block with it. The pump is rather good so don't wast anymore money. The rad that comes with it is good, nice and thick so will cool your GPU and CPU fine with headroom for overclocking.
 
How did you find the tubing that came with the EK kit, Crater? I heard it was quite prone to kinks. If that's the case, it might be worth getting some better tubing if you have any decent bends in your loop, Bender.
 
I will see how it all works together, and btw, i was thinking. I am reading the instructions right now how to setup the loop, what would you say if i put it like this? RADx2->CPU->RADx1->GPU->RESERVOIR->PUMP->RADx2 ?? Is it possible or would i have to connect RADx2 with RADx1 directly?

(RADx2 as in 2x120mm and RADx1 as in 1x120mm).

P.S. I read that it is a good idea to flush the radiators with hot water then with distilled water, is that correct?

Or buy anti kink coil
 
Now i would need some help because Zalman Plus seems too small for two RADs :) and i don't want them to store outside the case... Do you know any good cases that would fit everything inside?

Yep tubings crap, i got i think is 3/8" fitting which are a tad small. I would get better/lager tubing and fittings.

On a side note, the CS is crap!
