Taking the Plunge: Converting my ATCS 840 to Water Cooled

post #1 of 27
Thread Starter 
So I figured after many years of building PC's and case modding it was time to step up and spend more money on my rig than I spent on my first car (that's not saying much). As a noob I've been searching and searching for several weeks for information on water cooling and thought, for me, the best thing would be to start w/kit and build up from there. Here's the rig that I'm starting with:



It's an i7 on a EVGA SLI board w/couple of EVGA ref GTX 460's and one of my old GTX 275's as a physics card.

I'm getting the EK-KIT H3O - Supreme HF 360 kit (although I could have clearly bought custom for about the same price) and a Koolance 460 water block to start. I'll just do one card for now and in a month or two punch out another $100 for the other block.

I've been watching videos and reading up on things so when my stuff gets here next week I'll start posting in earnest. I suspect I'll soon have fittings and tubing supplies all over the place like I have cases and other PC parts now...wish me luck!

This will be cool, I was looking at getting an 840. By the way the GPU names are GTX 460s not 460 GTXs. I don't know it's just one of those things that grinds my gears haha.

No need to grind (I updated). The 840 is a classic case with excellent air-cooling and it's massive. Although the case isn't heavy...with all the equipment in it's a beast. I took it to Pax East last year and will never do that again. Although I usually mod fan holes and the like, there was no need on this case. I did add some MNPCTECH case feet but after the water cooler equipment is in I'll probably go with wheels. My entire solution will be inside the case. Looking at flow meters and other accessories now. So much stuff...so much money...

Yeah I was looking at it because I think its a great water cooling case. Sorry if you took offense to what I said about the gtx 460s it's just one of those things for me if you know what I'm saying. I'm assuming this is a build log type thread? By the way the supreme LT is not that phenomenal of a block. if you can I'd go with the HF it's one of if not the best performing blocks on the market. The LT will work fine though.

No offense at all. Yes it'll be a build log and I'm still ordering a few more bits (compression fittings, some swivel nozzles). I read a few reviews and watched this:

...cooling wasn't that much better w/HF but it might make sense to get the HF because eventually I'll cool more components and won't want the flow to be constrictive.

Truth is I'm just interested in this to tinker around and it's the next logical step.

BTW...where in Colorado? I lived in Colorado Springs for three years a long time ago...just down from Norad and north of Ft Carson.

To be honest, if your going to go all out, don't buy a pre-made watercooling kit, build your own.

By the way, your going to need more than a single 360 rad for your 920 + 2 gtx 460's.

Even though the 460's run cool I'm sure you're right...I'll build it w/single 460 and see how it goes. I did the kit thing because the bits were decent and it saved me a few bucks (shipping costs basically). 've also got the i7 OC'd to 3.6 w/small voltage adjustment and its running pretty cool w/H50 right now (in Crysis I never come close to warning levels). The i7's are a dream to OC...it's not like the old days where you putzed with all sorts of settings.

I suspect I'll eventually swap everything out as I get more comfortable...but WC sure isn't for the feint of heart (or pocketbook). I was originally looking at an all Koolance solution but I get the sense that even those are quality components that look great, they're not demonstratively better than others...and it seemed their prices were slightly higher too. The EK bits seemed decent and were less expensive so I did the impulse thing and clicked "purchase".

Actually, no, that amount of rad is perfect. 460s aren't that hot, and a good 360 can handle more than that, overclocked. EK rads may not exactly be high end but they will handle that job with headroom left.

Yeah the 360mm should handle that fine.

Q: So if I run a typical 840 setup the rad goes on top (not sure if I should pull or push air into the case), I follow normal cooling conventions (terms of flow), I remove the three 120mm on the inside of the case (plus the one on the H50) and I remove the two 230's up top...will the one 230 on the front be sufficient to keep air flowing in the case (to avoid dead spots)?
