Top Tier CPU Air Coolers Q3 2015: 9-Way Roundup Review
by E. Fylladitakis on July 6, 2015 8:00 AM ESTThe SilentiumPC Grandis XE1236
SilentiumPC is a Polish company that is fairly well known in Europe, yet with virtually no presence in the North American markets. The company was founded in 2007, aiming to provide a wide variety of cooling and case solutions at competitive prices. For the means of this review, SilentiumPC provided us with the Grandis XE1236, which currently is the best cooler the company produces.
The Grandis is supplied in an aesthetically plain but effective cardboard box. There is nothing of note regarding the appearance of the packaging, as the only artwork is a picture of the cooler itself. It does offer good shipping protection though, with the cooler protected inside a clear plastic shell and the bundled items grouped in secondary cardboard boxes.
With the company focused on minimizing the costs, we did not expect the bundle of the Grandis to be grand. Nevertheless, besides the necessary mounting hardware and wire clips for three fans, SilentiumPC provides a tube of quality Pactum PT-1 thermal compound and a Y 4-pin fan power splitter. A small wrench tool is also provided, necessary for the installation of the cooler.
The Grandis is supplied with two 120 mm cooling fans. Both fans are mechanically and electrically identical, with black solid frames and tinted black blades. They have been rebranded and it is difficult to recognize their OEM. Their electrical specifications, speed and sleeving type match the Power Logic PL12S12L, yet the acoustic ratings are worlds apart.
The Grandis XE1236 is a symmetric dual tower CPU cooler, with relatively narrow towers for its class. The fins of both towers are perfectly symmetric as well, meaning that both their front and rear sides are identical, mostly straight with shallow indentations near their center. SilentiumPC died the top fin black, obviously for aesthetic purposes only, but it does not cover the copper heatpipes.
Up to three 120 mm cooling fans can be installed on the Grandis, using the provided wire clips. The wire clips are strangely shaped and very wide, expanding above and below the cooling fans. This makes them flimsy and prevents the movement of the front fan upwards to offer clearance for the RAM modules, if necessary. The center fan will have to be removed for the installation of the cooler, as there are no holes for a screwdriver. Do note that a Philips PH2 screwdriver with a shank longer than 145 mm is necessary for the installation of the Grandis, which is not supplied.
The base of the Grandis XE1236 is about as simple as the rest of the cooler is. It is split into two parts: the narrow lower copper part serves as the contact surface and the aluminum/steel top part provides mechanical cohesion and retention. Six 6 mm copper heatpipes expand from the base of the cooler to either tower on both sides, evenly spaced at the right and the left half of each tower. In order to keep the costs down, SilentiumPC did not plate the copper parts of the Grandis. The quality of the contact surface is disappointing, not because it has not been polished at all but because there are multiple machining marks visible with the naked eye and easily feelable by touch.

I expect many R9 Fury X users are shopping for large air-cooler now as they have to give up their AIO CPU-cooler to Fury.BTW, I really wish you added a Hyper 212X as reference.

You could just buy a case like the Fractal Design Define S, which could fit two separate 120mm CLLC in the front, allowing both to get fresh air.Flunk - Monday, July 6, 2015 - link
I'm a bit disappointed that you didn't comment on the install process on any of the heatsinks. I recently bought a Dark Rock Pro 3 and while I love how quiet it is and the temps are actually lower than the Corsair Hydro H80 it replaced, the install process requires you to screw the heatsink in from the back of the motherboard. That and the size of the supplied backplate made the heatsink install more difficult that is really necessary.If you buy a Dark Rock 3 Pro I recommend removing the motherboard from the case entirely and installing it by flipping the heatsink upside down and balancing the motherboard on top of it in the correct position. This makes it fairly easy to screw in. But if you are using a normal thermal paste you might need to put it on the heatsink instead of the CPU heatspreader. I use IC Diamond and that stuff is so thick that it just stuck there upside down for long enough to finish mounting the thing.

Yeah, this is actually quite important. Noctua's mounting brackets are, by far, one of the easiest to work with.'nar - Tuesday, July 7, 2015 - link
I never gave it much thought. Installation is such a small concern to me, maybe I do this more than most, price and performance are preferable. That said, I still think Noctua's mounting can be improved, it seems unnecessarily complicated to me. First off, you really do need to replace the plastic bracket, there's no way around that. But secondly, why include a 140mm screw driver? Why not make the screws 140mm taller? Then you can just use a common screw driver, even a stubby or a pocket knife. And make them captive so they do not fall out and you do not need to line them up. These will certainly add to the cost due to extra engineering time and unique screws.Beany2013 - Wednesday, July 8, 2015 - link
Because the 140mm screwdriver:A: Is cheaper than re-engineering the entire product
B: long screws are *very* easy to cross-thread due to the extra sideways torque you can apply when inserting them.
I *do* like the Noctua setup system. It's strong, comprehensive, and lets be honest, you only do it once. I'm pretty sure that any gotchas with installation were caught in the descriptions of each cooler, too.

For the Macho Zero especially, I'd want to see the tests conducted (additionally) in a vertical motherboard orientation (as you'd have in most tower cases), since convection may have an effect on performance. It may also reveal differences in fan noise due to bearings rubbing more or less on different surfaces.'nar - Tuesday, July 7, 2015 - link
Not likely. Convection is slow. Any fans will blow away convection currents. Besides, orientation is strictly a "case by case" basis and beyond the scope of an empirical HSF comparison.Fan noise due to orientation may be good to check for though. I doubt it will be any different, if it is, the aberration should be noted.

wow, cpu cooler roundup! It seems so rare to see these nowadays.
