Shocking news: ATX specs are in inches. When you see decimals after millimeters it's due to conversion.

 


:D Still needs to be forgotten. At least the metric system makes decimals SIMPLE enough.

Soyo tried to do that with motherboards and ended up making boards where the holes didn't line up with any of my cases :)

It's easy to do metric-only with whole products, such as a whole car, until you get to something that needs to fit standard replacement parts. For example, we're not getting rid of inch-sized rims because there are too many cars on the road with inch-sized rims. And that leads to the weird metric/inch combo sizes such as 295/50-17. The old inch spec for the same tire, 29x12-17 was easier to read.
If I wanted to figure out if a 295/50-17 tire fit the body, I'd need to multiply 295 x 0.50 to get the section height, then multiply by two, and the add the rim height. I could convert the section height to inches or the rim diameter to millimeters, and since BUILDINGS in the US use inches I already have the inch tape measure. Etc etc when you try to fix something you only make it more complicated.

I've got an H100i in the inside roof of a CM haf 912 case mounted with a 200mm fan on the roof. Seems to do just fine pulling the heat out of the case and radiator. Also quieter than dual 120s. My 5820k runs overclocked to 4.2

Even though I said the air cooler seems better, I still got a closed loop liquid cooler. The H80i. It doesn't seem to be as badly affected by Dust. It also has an additional weird side effect. My case is thick aluminum and glass. My radiator uses metal screws attaching to the back of my case. Now my entire case acts as a heat sink. When the CPU gets hot, the entire case gets hot.

Since somebody bothered to drag up this old thread, figured I'd share my own thoughts.

Mobo: MSI mpower Z77
Case: CM 690 II Adv
Cpu: i5-3770k

The 3770k is a new addition, was previously a 3570k that flunked the OC lottery so badly 4.3@1.208 was the highest stable OC I could run. Picked up the 3770k for a song and so far have achieved 4.6, p95 26.6@84°. This is, in my mind a little high for the Corsair H55 I'm currently using. I love this little cooler btw. So. I grabbed a Raijintek Tisis that was on sale for an unbelievable low price. This twin 140mm cooler is massive, and I do mean massive. Easily taking up most of the space on the top half of my mobo. According to Raijintek, its a 350w+ cooler, this should easily keep my 3770k in check, right? Wrong. Upon install (yes, it'll easily fit in the case, has better part of an inch clearance to the sides of the case, even with a tower over 170mm tall), what I discovered, to my dismay, that the cooler does not physically fit on my mobo. Bolts for lga1155 bolt right in, ram clearance is not an issue, the mount is easy, and all looked good until time to actually drop the heatsink on the mounting brackets. This is where the problem starts.

The MSI mpower has 3 large, heat-pipe connected, heatsinks surrounding the cpu socket, the one closest to the back panel i/o's being the largest. Guess what the 6 heatpipes on the tower hit, yep. I need close to 4mm more space around the cpu in that area. I cannot physically mount the heatsink, aligned on the cpu, because the towers heatpipes hit the mobo heatsink. Just what I wanted. The hottest part of the tower directly contacting the heatsink on the mobo designed to keep the mosfets cool. My answer? Turn the heatsink 90° and face the exhaust out the top. No worries, should be good, case has room. Wrong again.

The tower is so massive, that it is physically impossible to put the initial fan in push without having to lower the gpu to slot #3 in order to get enough clearance to get any airflow near the initial fan. So the fans were installed pull. And here is what I found.

H55 @4.2, 1.16v: 37° idle, 74° p95 small fft 1/2 hr test.
Tisis @4.2, 1.16v: 40° idle, 80° p95 small fft 1/2 hr test.

That's a crying shame. Obviously the airflow in pull configuration is nowhere near enough at the Tisis 2x 1000rpm fans to effectively operate. It needs push. And in my 72°F room, even with 2x 140mm I intakes, there's just not enough for pull in a vertical mounted tower.

So, even though the tower is massive, physically fits inside the case, it's not able to do the job intended because of mobo clearance. Don't know if this is an issue with others, having a less high end mobo with smaller heatsinks, but I've not ever run into this particular issue before. Usually ram clearance is the issue with such massive twin towers.

I think I'll stick with CLC's, even the h55 (hyper212 EVO equivalent) does a respectable job on a mild OC, leaves plenty of space for airflow in the case, is invisible (rad sits above the frame under the top plastic shroud) and generally adds to the looks of the pc, simply because I can see the majority of it, its not covered up by a massive tower.

Clc's cost more, sure, some claim noise issues with pumps, some say stock fans suck (most do), but generally speaking, what the fight between air and aio boils down to is user happiness. To each his own. The NH-D14/D15 is big, works extremely well, at very tolerable noise levels. But thats not got as much to do with the heatsink as the fans. Slap those fans on a h100i or h110 and then talk to me about clc's being noisy at load.

Do they all work the same? Roughly, yes. And each has its own advantages and disadvantages. End result is what's right for 1 person isn't necessarily right for another. Make your own choice.
