cooling suggestions for I7-950 and sli gtx460's in a haf922 case !!

post #1 of 13
Thread Starter 
Hi All ,
I'm looking to really water cool my rig, runs hotter than I like and no room for much ocing, I7-950 currently h50 cooler and sli gtx460's g1 sniper mobo

goal : max performance and cooling in limited depth/thickness with a 240 rad and 120 rad(no depth/ thickness issue here) while staying under 35-38db noise, and looking to oc 4g+ and the gpu's:thumb:

first issue is from top of ram to top of case we have 71mm clearence thus the 240 rad and fans cannot be thicker or deeper then 70mm combination
preferrably a little less, and I want to stay with the 240 size and no or minimum mods

a few I have looked at xspc ex240 34mm thick with 25mm thick fans 59mm total
black ice extreme II 240 40mm and 25mm fans 65mm total should out perform the xspc ex based on total area ?

I know there are a few 12mm and 20mm thick fans which could open some doors but not much cfm from these so will they work with the 50mm thick + rads ?? while still cooling enough ??

not against mounting fans on top of case also but only if push/pull is required or suggested,

also I will be adding a 120 in the loop mounted in the top back of case (no thickness restriction here !)

so looking for suggestions on best 240 rad and fan combo for the top inside mounted rad. and also for the 120 inside top/back of case

the loop i want to build is 240-res-pump-cpu-120-gpu's-240 or per better suggestion !! single loop !

the gpu"s are limited to the xspc fullcovers (only in stock blocks i can find) my cards are reference!

I dont believe two 460's will make much more heat then 1 strong 580 the 460's are known to be fairly cool gpu's except the top card in tight sli setups lol !!mad.gif and maybe only water the top card ?? bottom card runs 65-70c max

looking at cost/perfomance ratio also so keep it real !!

So Suggestions for 240 and 120 rads and fan combo based on above info would be highly helpful along with pump -cpu block and res suggestions : : I wanted to go with a xspc rx240 kit but there too thick and no xspc ex240 kit that i can find. besides i know these kits have weak pumps!

Thanks ALL !! looking forward to your help thumb.gif 74 Bronco

M8 ive covered your queries albeit from my point of view in my thread(direct reply to you) thumb.gif have a look.
It also covers your Radiator/fan setup query with proof, hopefully this will point you in the right direction

PS:btw, you have loads of space between your ram and the top of your rig(no modding needed) to cool your 240, you could run a pair of GTs (1850) and you'd be set-hell i wish i had that room to play with, i had 51 mm lol! Also i would go for XSPC RX rads since you have the space-they have a lower FPI and so you would have less noise problems.Ignore my slimline fans please (same applies to anyone reading this lol) they are my personal addition that aren't really needed even if they can run on their own for light jobs- 2 x 25mm GTs would be fine for your cpu, considering you plan to run a 120 rad for your gpus.

I guess what I need to know or want help with is fpi versus thickness versus fans lol the rx is 53mm thick with 25mm fans pushing exceeds the 70mm so whats the next best perfomance gain in cooling then ?? running slim 12mm fans pushing on a rx and adding fans on top pulling or reducing rad thickness to sub 45mm and 25mm fans . a ex is 34mm split fin and a little more fpi which will actully cool better ? the 34 mm ex with optimal fans or the 50mm+ rx with less than ideal fans ??smile.gif and then what would be ideal flowrates from the pump with said rads ?? lol so so many options and so little money or time lol and thanks for the reply !! I liked your clean build btw about the only real difference in our builds is my cpu 1366 socket 17-950 run way hotter then your sandy, cheers.gif

IMO id go for the RX with a pair of GTs (rpm is your choice, but id get the highest rpm on sale)-you do not need push pull to get good temps from it (link :http://martinsliquidlab.org/2012/01/15/radiator-shroud-testing-v2/) read the info from the link, it will explain how push/pull truly works and the various combinations that you can use-you will notice that FPI/rpm &CFM each play their role).

My reasoning behind you choosing the RX is because its both thicker than the EX and has a lower FPI, thus good cooling with low noise-one pair of fans in either push or pull setup would suffice-again read the article/test. your decision on whether you use push or pull will be based on the noise factor seeing that the difference in temp will be no more than 2 degrees Celsius, again read the article m8, dont take my word for it lol!
Another thing, imo, id actually use the 120mm (get the thickest possible based on your budget) for your cpu and use the 240 on your gpus -the gpus emanate more heat. also since you will have more space you can drop a monster fan or fans on your 120 to compensate for the rad size. Its all down to your various constrictions, ie: budget/case space/noise vs cooling etc.

As for pumps, im not as well read up on the topic, all i did was learn the basics -ie pressure vs flow, and what pump would be suitable for my needs etc. i got a great deal on my pump and it will also cover me adequately when i introduce my wc gpu. My advice would be to go for the Laing D5 pump or the DCC 2 or DCC 12v, they are reliable and what most people use (not that it should count), they will also cover your flow rate/head pressure 'anxieties'. Also remember that flow rate can be restricted by your setup, ie whether your components restrict your flow or not-again do your research m8
. My pump is a different breed of animal and off the beaten path. My advice to you is not to rely on the forums that much initially, but to go away and read, ie research your intended rig and its needs, and then return to the forum armed with knowledge that you can then put to the forum-then you will get more replies to your specific questions thumb.gif

ive answered your queries on the lack of gtx reference card wc blocks- xspc are not the only ones on the market.....

The EX and some quality fans is going to perform FAR better than an RX and 12mm thick fans, the 12mm thick fans move very little air and lack any real static pressure, they're all but worthless for a radiator. If you're on a budget, Yate Loon medium speeds (or high if you don't mind a bit more noise) would probably be one of the cheapest options for fans, they're the best bang for the buck. If you're looking to spend a bit more on fans, there's always the XSPC fans, or if you really want to go nuts, GentleTyphoons are always popular. For the rear radiator, it's really hard to beat the performance of a Black Ice GTX, though it's going to perform poorly with slow / quiet fans, so with your volume requirements, stick to something with a low FPI. Another EX series would be just fine here, a total of 3x120 EX series should handle that heat load just fine.For pumps, I'd probably use something like the MCP-35X for this setup, though a D5 should be just fine as well. On the GPU block subject, there are other 460 blocks than the XSPC ones, but the XSPC blocks perform just fine, and they're easily the cheapest of the options. For CPU block, I'd go with something like the XSPC Raystorm, it performs great and is very low restriction, which is nice in a somewhat complex loop like this. I'd run your GPUs in parallel, it will increase the flow rate in the rest of the loop at the cost of the flow rate to the GPUs, which aren't particularly sensitive to flow so it's not an issue.

Er not true my friend, i am able to use my 12mm fans alone for light work ie surfing the web/watching vids, and my temps never surpass 32 degrees. for 'proper' cpu work i use my GTs, and not the 12mm fans.The 12mm fans use less electricity and so i cut down on power consumption during light usage-every penny counts m8 wink.gif

That having been said, yes you are correct about the SOLE use of 12mm fans with ANY radiator, that would be useless, but the EX rads(i use one myself) have a denser FPI than the RX radiators and he was also interested in keeping the DBs down, hence RX with GTs=basically the same as EX with GTs, the only difference being that with the RX the DBs would be lower; the difference in temps between a 240 RX and a 240 EX are minimal at best, what comes into play then is available space/price and noise IMHO.

He stated he's unable to fit an RX series with 25mm thick fans though, if the options are RX and 12mm fans, or EX and 25mm, the EX wins easily, as you mentioned using the 12mm fans exclusively just doesn't cut it for anything more than light use. As for power consumption, you could always use a fan controller to cut down your 25mm fans rather than using 12mm fans, I'd imagine you'd save even more power that way, though I don't have any 12mm fans laying around to truly test that.

Ok were are at crossed wires here biggrin.gif
I meant that he could mount his fans on top, instead of inside, that's why i suggested the RX since space would then not be an issue-if he wants to solely do an internal mount, then i stand corrected and your option would be the best for his dual radiator. As for the use of a fan controller i cant comment on whether his budget covers that-but that would also be a viable option (i use one myself) I think that he was confused with my use of both sets of fans, and he thought that i used them in conjunction with one another(many people that have seen my rig make that mistake, they don't realise that i use the 12mm fans purely for auxiliary work)-i pointed out in one of my earlier posts that 12mm fans are not the way to go for serious water cooling,and so don't follow me, i hope that he has got the picture now thumb.gif
