CM 690 II - cooling potential using Internal rads

Hi there,

New to the forums and wanted to run this by the more experienced folk here...

I initially found Tom (no, this isn't some religious conversion thing...well, maybe a little
wink.gif
) while doing some research on the water cooling potential of the CM 690 II case. I'd gotten this case as part of a bundle and hadn't directly picked it myself as I usually would. Blame it on boredom and the right bundle deal at the wrong moment of weakness if you will
wink.gif


Anyway, I have my rig all working great currently with a 2500k @ 4.6 cooled by an Antec Kuhler 620. I also have a GTX 570 on stock air cooling. This on an Asus P8Z68-V Pro Motherboard.

Now, my system runs well but a little noisy when either the CPU or GPU are working hard, though not too bad by any means. My 570 was originally paired up with my Q6600 @ 3.6 in my old system. Since moving to the 2500k however it's really given the card its wings so to speak. Due to the strength of my CPU I'm considering adding a second 570 to run in SLi, however this will start giving me heat and noise issues I am sure. I've been tinkering with trying my hand at watercooling for a while now, purely because I find it fascinating. I helped a friend a while back design and build his water cooled system and it was great fun...

I thought that if I'm going to go SLi I might as well work on a proper cooling solution while I'm at it...I had thought about just water cooling what I have but I do fancy giving SLI a go this time around.

I think the CM 690 with one thin (25-30mm) 240 Rad in the top and one thicker (50-60mm?) 240 rad in the base should provide adequate cooling for both CPU and a single 570 - both with a reasonable OC applied. However I think that adding a 2nd 570 (albeit not pushed clock-wise, having the pair and all) may well be a little too much for those two rads alone.

I've checked out Tom's various vids, including the Snowdrift ones, and have found his work and enthusiasm inspiring...and I want to do something similar, though with my own touches of course.

I'm looking to build something smart, tidy and all-inside but it has to still provide effective cooling.

My Kuhler 620 is only a single thin 120mm rad yet it's doing an admirable job on my 2500k @ 4.6 - very pleased with that - so having a 240 rad for the CPU is in effect doubling the cooling area of what I have now. Then if I had a thick 240 rad (so double capacity of the thinner 240) for the GPU's that might just work - I mean if a 25mm 120 rad can cool a 2500k @ 4.6 then four times that capacity should do a pair of 570's right? I know based on the loop that all rads help cool everything in effect, but the breaking down by component helps me visualise overall cooling.

So, based on your experience, is asking a pair of 240 rads, one 25-30mm the other 50-60mm thick, to cool a 2500k @ 4.6 and a pair of 570's asking too much? Would I likely not see any improvement in temps?

For the record my 2500k hits low 70's in IBT, v.low 60's in Prime 95, and the high 40's low 50's in most games...pretty good for a 25mm 120 rad (push/pull).

Any thoughts or suggestions are welcome and would be appreciated.

Cheers,

Scoob.
 
Hi again,

One thing I'd like to add to this (in the hope that someone will respond
smile.gif
) is that I was given an EK-RAD-XT-360, which is 390mm in length overall, 125mm thick and 45mm deep.

I know I cannot fit this internally in the CM 690 II, but possibly someone has some advice / experience regarding fitting what is in effect an over-sized rad for my case. Possibly some external mounting maybe?

Cheers,

Scoob.
 
Hi,

Thanks for the replies!

Sieb: cheers for the links, something like that might work. I don't however floor stand my PC. I could pop it on the desk but would lose my 2nd monitor - possibly I could juggle things around for it to work.

mayhem: I have considered getting the dremmel out and attempting to top-mount the rad. Though my dremmel skillz are in their infancy...I can port exhaust headers quite well mind!

My friend got himself a 360x360 rad (yes, 9x 1200mm fans TIMES TWO for push-pull on that!) for which we made a bracket so we could suspend it off the right hand side of his Cosmos S case. It had little feet on the bottom left of the rad so hold it away from the case so it hung upright. Monster rad that!

I will have to have a good think about how best to implement this, it's good to know that brackets etc. are available to help - I thought I might have to make something as we did for my friend.

Cheers,

Scoob.

Do not dremmel use a jig saw that's the mistake a lot of people make they use a dremmel. A Jig saw will be neater and will all so produce much better results all so it only takes 10 min max to do it all.

(maybe longer if its you first time) just take your time and you will be fine. Measure and mark, then double check every thing before cutting. Drill holes in the corner so you can do much neater lines.

Noted: I appreciate the advice!

I've only used the dremel to cut plastics and light metal so far, as well as using a tungsten bit to port the headers on my Scoob last year.

Appropriate tool for the job, very important

I imagine I can hire one, or even buy one relatively cheaply these days?

Jig saws around £20 will do the job.
 
I wouldnt bother trying to put a 360 in the roof because there IS NOT room for a rad that will be worth the hassle. Max rad thickness with one set of fans is 30mm thick. So RS sized XSPC rads. Youd still need a full sized 240mm rad in the floor to even have a hope of cooling it all.

Basically you would be better off getting a decent external set up. Be neater, cooler, quieter and a lot easier for you to put together.
 
just spoken to tom my 690 is the first version and fits. apparently the version you have is totally different and will not fit. So i do apologise .... (face palm moment)

Scoob looks up from his newly "customised" case...reads posts...ah! Lol.

Thanks for clearing that up Tom, appreciate you taking the time to post. Not to worry mayhem, I imagine it's difficult to keep up with all the case varients out there!

While I am keen to practice (plus this stuff is FUN) by popping a loop into this case I think at best I can just cool what I have, i.e. CPU and one GPU, with internal rads at least. I'm not sure I'd get good enough temperatures to be entirely satisfied or be able to push components further. I get what you're saying regarding an external rad - this is exactly what we did for my friends machine using a huge 360x360 rad externally with 360x120 in the roof of his Cosmos S. Very, very effective cooling of his CPU and 2x GTX 480's, however not a neat build. I really wanted any loop I put into this case to remain internal, purely for neatness and looks more than anything, though that of course compromises cooling.

Maybe I'm best off sticking to my original plan of a bespoke build from scratch for my next build with watercooling of CPU and dual GPUs in mind from the start. I've recently viewed you excellent video review of the Caselabs M8 Tom, I confess I was actually getting quite excited at the prospect of doing a build in such a case. Previously I'd been considering the Silverstone TJ07 as my ideal candidate for a water cooling case - again with an "everything iniside" approach.

I'm happy with the performance of my current PC using the Kuhler 620 for the 2500k CPU @ 4.6 and the GTX 570 on stock cooling. I can save my money for my "proper" build using likely a high-end Ivy Bridge chip with hopefully a pair of pre-blocked GPUs from AMD or NV, whichever floats my boat at the time.

The problem is of course that I WANT to play around with my PC...it's resisting that which proves to be the biggest challenge. Don't be surprised if I'm back on here having spend £500 on watercooling kit for the 690 II - though I will just be cooling the CPU and ONE GPU...probably...maybe I should look into external rad mounts..? Lol.

Thanks again for everyones input, appreciate it.

Yeah ST have them in black and can order in white. Ive actually got one coming

Cool,

I had a little look on Special Tech earlier but didn't see it under radators - I'll have another peek later when I have more time. Is this an item you plan to review?

Of course its a review dude lol. I dont buy hardware

Doh, yeah...lol.

Ok, thanks for the link. I did see that one (and the 120 vers above it) however the picture in your post shows it with some tidy looking enclosure/grill fitted rather than as a naked rad, hence my confusion. I assume these are one of the various accessories available for it? Though it doesn't appear to be listed, feet and wall/side case mounts are though.

I'll wait for your review

Oh yeah, I think it was the Phobya Extreme Nova 1080 we fitted to my friends build, hung off the side by some custom-made brackets.

Cheers,

Scoob.
 
Review wont be done any time soon and yeah you can buy grills. 9x140 and 4x180 options are available.

They are not cheap but are probably the best looking external option available.

Ok cool, no worries. Certainly looks like an option for a nice tidy build with those grills in place. Reckon it'll manage my CPU and a pair of 570's quite happily that! Would have to re-think my plumbing as well as cable management for the fans...guess some braiding would be in order...

Happy to spend a bit more to keep things tidy
