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.

They did one of these round ups with the 212 Evo or + a while back, also involving high ends from Noctua (U14 and U12S I believe). They found that it doesn't quite match up, but I know it got a mention for exceptional performance for cheap. I think it falls behind more in noise than performance.It definitely would have been interesting to see it in here, but nevertheless, thanks for the review!

I usually undervolt the fan a little - takes care iof any noise issues.Arnulf - Monday, July 6, 2015 - link

I would have also liked to have a "decent" CPU cooler like that included, as well as the stock Intel/AMD HSF. It's great seeing how these coolers stack up to one another, but it doesn't truly quantify how much of an improvement you're getting over a cheap alternative, or the stock fan. For the record, I haven't run with a stock fan on any main PC I've owned in the past 15 years, but I would be curious to see how much I'm actually gaining.Araemo - Monday, July 6, 2015 - link
Especially given the raw value of the Hyper 212 Evo at $30, it may get within a degree or two of some of these for half the price or less... which is why my last build had the Hyper 212+ (It's been a few years) - I could have gained maybe 5C by spending 4 times as much.. which didn't seem worth it to me.TheJian - Tuesday, July 7, 2015 - link
AGREED. I have one, and at $29.95 from newegg just a few months ago on sale it was an AWESOME deal. i4790k can do massive oc's with it and even at full load is not terribly annoying with my 5850 causing most noise when gaming. This is still a top seller and for good reason.LittleLeo - Thursday, July 9, 2015 - link
Since its about the most popular cooler for gamers that would have been nice.jay401 - Monday, July 6, 2015 - link
I'm actually really glad to see this article, it's been ages since I've seen a good CPU air cooler roundup and sockets have changed several times over the years so it's nice to know what works well these days.jmke - Monday, July 6, 2015 - link
air cooling has plenty much run into a wall; heatpipes to copper base, aluminum fins on the heatpipes, put 140mm or 120mm fan... there is not a lot of wiggle room, so performance of those that follow this recipe is very close.differentiators now for most part are: socket compatibility, price, installation method. Raw performance/noise is no longer the focus imho if you want a successful product

It's not so much socket compatibility, so much as how compatible you can make your heatsink against mobos that have poor design choices.Although not as common on mATX and larger boards, mITX suffers a lot from this, because manufacturers attach fragile bits onto the back of the mobo, near the CPU socket, that interfere with the mounting bracket. Either that, or the CPU socket is placed too close to the PCIe, etc.
That Reeven Okeanos is something I haven't seen since Athlon 64 days, which are heatsinks paired with a stupidly loud fan. Look, if I wanted a heatsink with stupidly loud fan, I would buy an amazing heatsink or watercooler first, then attach the stupidly loud fan to that, instead of some mediocre heatsink with a mediocre fan.
