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 agree. It would be helpful to know how the 212 compares both with regards to cooling and quietness. I typically prefer "quieter" so I'd be curious to know how much better the "Dark Rock Pro 3" is than the 212... is it $40+ better?Eidigean - Monday, July 6, 2015 - link
I actually bought the 212 and added a second fan to it, not because it was cheap, but because it would fit between the 2x2 banks of memory on my Rampage IV Formula perfectly (with 1 mm of space on either side) allowing the tall memory heatsinks to rise up, and inconsequentially get a breeze from the fans. The CPU runs nice and cool (and quiet) with a modest overclock.I'd get the offset Noctua NH-D15S if I ever upgrade from a 4 core 3820 to a 6 core 4930K.

Exactly my thoughts. The Cooler Master Hyper 212 EVO needs to be included in this test, to show exactly what 90% who buys CPU coolers are missing out on, or eventually not missing out on.randomlinh - Monday, July 6, 2015 - link
I'm confused about your complaint. What's wrong w/ the 212? What's wrong w/ saving $10 for 1 deg celcius difference?I genuinely don't know, I have a 212 from almost 4 yrs ago? It works. It's quiet (for the time). The only complaint is if I try to go super small form factor, it won't work.

If it were only $10 I might agree with you, but when it's half the price, and sometimes a whole lot less, it makes a lot of sense. I looked at the Noctua when I built my 5820 last fall, and couldn't justify the 2.5x price. For $35, the 212 EVO is a great cooler. As good as the Noctua is, it's not two and a half times as good. That's why the 212 is so popular. It's in the proverbial sweet spot.andrewaggb - Monday, July 6, 2015 - link
I agree. I've bought several 212 EVO's and I've been very happy with them. I was mostly looking for something that would run quiet under load (without overclocking) and I think they've been great. I've used some less expensive coolers and they were much worse - so in my opinion it's the cheapest cooler that met my needs.Araemo - Monday, July 6, 2015 - link
Obsession is pretty harsh given the facts... I went and looked up a comparison over on frostytech, and it looks like the Hyper 212 evo is only 2C hotter than the Noctua chosen as the realistic 'best choice'.. for 1/3 the price. Given that my ambient temps change by more than that 2C over the course of a year, 2C is never the stability margin I use on my overclocks.Nfarce - Monday, July 6, 2015 - link
Except that the 212 is not a "premium" cooler. When you start getting into extreme overclocks like I have (i5 4690k @4.8GHz, or a 23% overclock) and into water cooling needs territory, the 212 falls well more than a 2C behind which is where it is on lower level overclocks (5-15%) on my chip.StrangerGuy - Monday, July 6, 2015 - link
Who cares whether if the 212 isn't a "premium" cooler when I can simply buy the 4790K at stock 4.4GHz instead of premium cooling to barely OC a 4690K past a 4790K. You overclockers STILL think there is tremendous value to be had with OCing when the 2500K ship have long sailed.Nfarce - Wednesday, July 8, 2015 - link
According to my benchmark tests in games and applications like Sony Vegas Studio, my overclock to 4.8GHz yields quite a bit of performance increase over the stock turbo of 3.9GHz. Oh and since I was on a budget and game about 80% of the time on that 4690K rig, I justified saving the extra $100 over a 4790K and put it towards a better GPU solution.And yes, I still have a 2500K build as well (not sure what that has to do with the price of ketchup), which used to be overclocked to 4.6GHz on that NH-D14 cooler (it is now relegated to backup duties and running at stock speeds on a Zalman 9700LED cooler). Which, incidentally, roughly equals the performance of my Devil's Canyon chip running at 4.2GHz.
