Need advice on a 1st time watercooling build

post #1 of 8
Thread Starter 
Hey everyone

I've been reading the forums and doing my research about water cooling for some time now and I finally have enough money to go for it!

I'm going to sell my HAF922 and get a Corsair 650D to go with my new WC build (This case is a dream! ). My main reason for going with WC is to reduce noise and heat. My priorities are "silence > performance > price".

This is what I came up with so far:
XSPC Rasa RX240 WC kit
EK 5870 copper block
XSPC orange UV tubing (10ft) 7/16" ID, 5/8"OD

I have a couple of questions before I order.

1.can I fit an XSPC Rasa RX360 on the top of the 650D? would it need some modding to fit (I don't mind some minor modding like with a dremel). If not, can an RX240 handle my CPU+GPU loop? or do I need to add another rad? I'd prefer to use only one.

2.I would like to use compression fitting on the GPU block only (I can use the included 6 barbs in the kit for the rest). I heard that XSPC tubing has weird thickness and some people had issues with Bitspower comp. fittings (I'm going with 90degree angled ones). Is it true? Should I just go with XSPC compression fittings?

3.I'm going with EK copper GPU block because I am not sure that the other companies blocks will fit my non-reference card (XFX 5870 1GB). Does anyone know of other better/cheaper alternatives that fit my card?

4. I'm trying to buy Scythe GT 120mm AP-13 fans but I cannot find them in stock anywhere. any thoughts on where I can grab some? Any alternatives that offer good silence/performance?

5. Will the pump be strong enough for my build?

This is all that i can think of for now. I'm still thinking if I should remove the bottom HDD bays for better flow. I'm sure I'll remove one.

Here's the case:



Thanks in advance!

I would go for the 800d and a 360. It will mount perfectly to the top, and you can use it on many future builds. The 800d also looks better and has a HUGE window on the side. Also, steer clear of any nickel plated EK blocks, they tend to commit suicide.

Since you're set on going with the 650D, I think you'll be fine with what you have there.

The pump included may not be the best out there, but it will be strong enough to push water around that small of a case, especially if you're just doing a CPU and 1 GPU.

For fans, check newegg and sidewinder computers. They'll have the best prices.

Make sure to get tubing clamps as well if you're going to use regular barbs, and if not just use compression fittings (yes, they're pricey but worth it.)

Also, buy tubing. Don't use the tubing that comes with the XSPC kit (it's cheap and kinks). I suggest Primochill or Feser. Buy at least 6 feet. The EK block will do just fine for your 5870. As the above poster mentioned, the pump is not the best (far from it) but it should do the job since your using a mid size case and only two blocks. The RX240 should easily fit inside the case (top) however a RX360 won't. You'll need to mod the case or buy an 800D.

I would check aquatuning for the fans. Takes a bit of time though for the order to go through, but then it was literally like 3 days shipping from Germany to Ohio. I just bought 6 AP-14's from them. Not to happy with them though as they are louder than my Noctua's they replaced. They do move quite a bit of air however. Might sell them though, haven't decided.

I was going for the 800D, but that thing is a huge case! It just won't work for me.
Do you know if modding the top of the 650d for an RX360 will be a major work? I don't have big space or any big tools for cutting (except a dremel 400). I'm willing to do some modding.

I am thinking of adding another card in crossfire when BF3 lands if my card can't handle it well enough. If I WC the new card, all I have to do is add another pump in the loop to replace the rasa pump?

Strobe, I was going for the Scythe GTs because I heard that they preform pretty good and they are silent. What were your noctuas?

I know the 800D is big, but personally I find water-cooling on a full-sized tower to be much more enjoyable than trying to make everything work cleanly on a smaller chassis. For instance, I started Water Cooling some years ago on a Silverstone TJ-09, which is about 650D sized or a bit larger. Not being able to mod easily, I soon ditched it for a Cooler Master Cosmos S and then a Corsair 800D. My requirement for any case is that it fit a 360 rad on the top without modding. Even if you can get a 360 rad in a modded 650D, you'll still have to deal with limited room for pump, res, tubing, etc. It can be done, but since this is your first go-a-round with a custom setup, why handicap yourself with a smaller case?

I have a 650D and, JMHO, modding the case to fit a 360 in the top wouldn't be worth the trouble. I opted to put a 280 up top and a Phobya 200mm Xtreme in front. A 280 will fit easily -- no mods required. The Phobya will fit but it requires drilling some new holes on the fan mount plates. I'm hoping that's enough rad to OC a CPU and a couple GPUs.
