WC Loop questions.

post #1 of 10
Thread Starter 
I have been putting together a loop for an upcoming build, and I have a few questions for the veteran WCers out there.

First, the parts I've chosen.



The pump is combined with the res, if you miss that.

Now, I plan on just having the CPU (i7 2600k) under water, but eventually adding a 6990 to the loop. What would I have to add to the 240mm rad (largest I can fit inside my case) to make that viable? I have space for 2 more 120mm rads, but one of the two is going to cut real close on space. Would I be able to squeak by with just an extra 120 or will I need to go external with another 240 or greater?

Also, how will the pump be fitted into that res? Kind of confused by it in regards to whether or not I will need fittings for it if the pump has barbs on it. Will the pump just kind of sit in the res with the intake just free in the coolant and then the barb be connected to one of the threaded out ports that I would need to attach a fitting to? I'm assuming the line into the res will require a fitting.

As a completely opinionated question, would red tubing look good against a blue mobo and blue LED fans? Or would I be better off going with black tubing in order to not "over-blue" the system?

Also any constructive comments on the parts themselves would be greatly appreciated.

I would say go for the rasa kit if that is all you are buying. The block is almost just as good, but will cost way less.

My only issue with the RASA kits are the supposed issues with the pumps failing after only a year or so. I figured with a completely custom setup I can choose parts that will last longer and provide better performance over the long run. Also I would be worried as to whether the RASA's pump can handle a CPU block and a GPU block.

I thought you had the rasa pump in your cart, didn't realize it was the bay res for the laing pump. My bad. I would say that setup looks pretty good otherwise.

No reason to worry about whether it will handle both. It will, there are many here that will attest to that. One other option, is to buy the Rasa kit, then sell the pump/reservoir in favor of a different one. But that's up to you. I considered the same, and chose to go a different route.

The difference in performance on the EK block, and the Rasa is about 1 degree. Not worth the price difference imho.

As for the "over blue" system. Well, that's subjective opinion. My system is mostly black, with touches of blue (a few cables in the bundle sleeved in blue, blue primochill tubing). Depends on your tastes, in the end, that's all that matters.

Alright, in regards to my other questions, do you know if a 240 + a 120 will be enough to handle a 2600k and a 6990 at reasonable temps?

I would go with thick rads if you want that setup, otherwise go with 2x 240s.

go for 2 RX240s if you can, or an RX240 and an RS 240

Yes, you should be fine.
Maybe RX or SR-1?
I would go 2x240's if they are thin rads that you go with.

So a thick 240 and a thick 120 would be fine? EK Coolstreams appear to be slightly cheaper than XSPC RX series rads.

Problem with 2 240s is I don't have space inside the case to fit that, I can fit a single 240 and 2 120s, with the second 120 being tight.

It may not be your style, but you could always mount a 2nd 240 externally instead of the other two 120's. Imho, I'd prefer that with the 6990 in the loop to a 120mm rad.

Reason being, I'd imagine your planning on using one of the 120's behind a front intake fan. Which will cause temps to rocket inside your case, that in itself will probably cause your NB/SB/VRM's to run a bit hotter than they would with a normal aircooled setup. Not a plus on the list when oc'ing is on the menu.

All in all, I'd rather keep my rad fans exhausting air out of the case, instead of pulling in heated air into the case. I understand the desire for aesthetics, but performance > looks. Though, ideally...we'd all like both if possible.
