I don't think so. The h50 with fans on high isn't relevant at all. I'll be using the h100 with the fans on a controller, and possibly replace the fans for something else. According to the reviews I've seen, the h100 performs very well with fans on low, and the performance scales through 200w+ overclocks.
What kind of wattage do you expect your Ivy bridge chip to generate with and without overclocking?
What are the exact dimensions of the proposed case?


With the disclaimer that this is all speculation, and not based on any kind of testing:
Probably around 60w stock, full CPU, 0 GPU use. If you kill hyperthreading and find the minimum stable voltage for stock clocks you can go lower, maybe 40w. I wouldn't be surprised to see 150w with hyperthreading on at 1.35v and 4.5 ghz. It would get worse from there, I would expect 200w at around 1.5v whatever clock that gets you. If you use on die GPU at all, add whatever that takes. I've seen an i7 920 over 300w (not precise, CPU load minus idle power at wall) at 4.2 ghz 1.5v, but the guy probably fried it by now.

The case is 20 cm wide, 41.5 cm tall, 34 cm deep. plus ~3mm material thickness to each dimension.

I wish cases like this were available.

Apparently the big manufacturers see enthusiast mATX a futile market.

Normal ATX would be fine with me too. Height doesn't really matter, lower depth would matter.
I just don't need 6+ 3.5" + 4+ 5.25" bays. I would like good cooling and low noise though. And support for long videocards.

Is chipset cooling or case temperature really going to be a problem? Take a closer look at that airflow sanity check image I posted(the one in color).
I am not able to fully figure out your diagrams. But to the extent I do understand them it seemed to me that you could perhaps accomplish more with less... that is house the same CPU & GPU power, with
less case (both in size and weight)...
less noise...
and less cost.

And I still harbor the believe that it is unlikely that either Corsair will approach the quietness of the Noctua. At the end of the day you have pump noise and also the high impedance radiators that you have to push air through. If you actually have 200 watts of heat perhaps you have to put up with that.

But I can't believe that, even overclocked, the Ivy Bridge will ever even approach saturating the Noctua's heat capacity dispersion capability.

Just my opinion.

Missed this post. The question isn't whether the Noctua is a good heatsink, it is, but the problems that pushed me to select a h100 are still valid. The first reason is mass attached to motherboard. The other issue is the direction of airflow, a c14 would pretty much require a side intake to perform anywhere near as well as it tested(I really dislike side intakes). I think I could build a case around that cooler, but it would look very strange and likely not perform any better. (I would turn the side panel into the back, all intake on back,exhaust on top. rear IO on right side panel with a door.) To contrast the latter issue, the h100 lets me move heat against the airflow, to where it's easy to add a vent, with an air cooler I'd have less surface area which can effectively vent heat, which restricts airflow options a bit.

Easy solution for this if you're building your own case: bolt the cooler to the mobo tray. All you'll need is long screws, spacers, and four more holes in your tray. There are variations on that theme that can be universal solutions, as well.

But I find it curious that you're worrying about mounting a giant, aftermarket heatsink to your mobo while blithely strapping another one to your video card.

I agree with that, but I've ready way too many scathing comments about those watercooling-in-a-can coolers (several specifically about the H100) to every try one. The best option, IMO, is to just widen the case enough to fit a 120mm tower heatsink. I know you want to keep the case small, but an inch or two in width seems like a small price to pay for the convenience, performance, and reliability you'd gain.

But if that won't work, why don't you skip the halfway measures and go straight to a full-fledged watercooling rig? I don't think it's that much more expensive, and If you use a universal GPU waterblock, you could save yourself a broken PCIE slot along with a broken mobo. When I looked into switching to water myself, I priced out a rig that could handle CPU+1xGPU for ~$200. It would be a lot less if you milled your own waterblocks, and that should be a breeze for a guy with access to a CNC laser cutter. :lol:


P.S. -- Woohoo! I'm no longer a lurker. Took me long enough. :roll:
