If the Noctua fits in it, then the case isn't really small or low profile -- ditto the NT06 with fan. You'll recall the NT06 was meant to be used w/o fan in a Silverstone SU05/06.BD Hopkins wrote:Thank for you taking the time to do this review. From a viewpoint that embraces relatively minimalist case dimensions and collateral cooling for the MOSFET and voltage regulators, I appreciate this two-part investigation into top-down coolers.
That said, why weren't the Noctua NH-C12P results included? I suppose you had to draw the line at some point, but it's only 3mm taller with a standard 120mm fan than the NT06-E included in your review.
If I'm not mistaken, all mainstream graphics cards are around 111mm in height, and if you go with the latest Nvidia family, you can add about another 25.4mm of height to comfortably accommodate the 6-pin power connectors (plus their wires, bent gently in an L-shape) that shoot up perpendicular to the length of the cards. From my perspective, a low-profile cooler is anything that comes in below about 136.4mm. I admit, however, that that my perspective is fairly rare as a scratch case builder. And as such, I don't know what heights many 'low-profile' cases support.
No, but this is not a viable option with most motherboards. The fan would ride too close to the surface to clear all components, particularly the NB heatsink.Monkeh16 wrote:Did you try fitting the fan to the NT06 between the fins and the base?
It looks like it might work on your test board. Could also work with a thin fan (Yate Loon do one).MikeC wrote:No, but this is not a viable option with most motherboards.

That's a good point about the intake clearance; I had not taken that into consideration. As it happens, the case I am building will not have any sort of vent above the drop down cooler, so I will be relying on the intake fan for fresh, cooler air.MikeC wrote:If the Noctua fits in it, then the case isn't really small or low profile -- ditto the NT06 with fan.

Lots of "desktop", SFF or HTPC cases don't allow for full height PCI cards or anywhere near 136.4mm vertical space. Even if that much space was available, you'd have to strike 25mm off for fan intake clearance unless there's a good vent directly above.
I was thinking the exact same thought as Monkeh16.MikeC wrote:No, but this is not a viable option with most motherboards.

Link (text below the charts)In order to see if the position of the cooler could affect performance, we simply put our case in the horizontal position. Under this scenario core temperature has reduced from 96 ºC to 77 ºC.
Look through their test methodology - the case they use has a big vent on the side panel. With the case/mobo horizontal that makes it a natural exhaust point. That probably contributed significantly to their results.Olle P wrote:Hardware Secrets recently reviewed the Silverstone NT06 and found that it was okay mounted on a horizontal motherboard, but abysmal with the motherboard vertical:Link (text below the charts)In order to see if the position of the cooler could affect performance, we simply put our case in the horizontal position.

I wonder how much this effect apply to the other coolers with similar layout...?

First: I'm pretty sure they run the tests with the side panel off. Otherwise the noise reading (4" from the fan) would become virtually impossible.Lawrence Lee wrote:- the case they use has a big vent on the side panel. With the case/mobo horizontal that makes it a natural exhaust point.
