I've used the Raijintek Zelos (for that is it's name, not the code number printed here) on both an Intel Pentium G and an Intel i3 system and would definitely buy another one of these for a small system that I wanted to be silent. It's a million percent better than the stock Intel fan in terms of assembly, height (for low profile media systems) and noise. The quietness, OMG! It's wonderful instead of listening to the whirring up and down of the stock fan. You can't hear this thing until you get so close you're worried about losing an earring! (note: I do not wear earrings. This was a metaphorical cautionary tale)
The only thing I had issues with were that the studs that screw underneath the motherboard are quite chunky and they push against the metal on my Fractal Node 202 case, lifting the mobo slightly. This can be remedied by getting your own nuts and screwing them down carefully with a thin nylon washer if you're paranoid about scratching the motherboard. This obviously only affects certain low-profile computer cases, so I can't grumble about it too much like some would.
Price: very good
Build: it's not a Noctua but you're not paying for a Noctua, so very good.
Performance: Keeps an i3 nice and cool with almost silence.
Assembly: Easy, with certain consideration needed for low-profile motherboard mounting (see above)
To fit you need to really remove the motherboard from the computer case (mine wasnt fitted into a case yet).
Fitting was fairly straightforward, i was using an intel S1200BTL server motherboard and an I3 3240 cpu:
After smearing some thermal compound on the heatsink (see below) i put a small amount in the centre of the processor. Then i gently put the bolts on the heatsink mounts through the motherboard heatsink holes, then turned it over and fitted the retaining bolts (i also added 4xred mica washers between the nuts and motherboard).
I did all 4 nuts up hand tight (without using the supplied spanner/wrench), as too tight can damage the processor/heatsink/motherboard. i used arctic cooling MX4 thermal compound.
I would recommend putting a small amount of thermal compound on the centre of the heatsink and smearing it into the gaps on the heatpipes, as this will improve the effectiveness of the heatsink.
Testing wise, im quite happy with the performance of the heatsink. idle temperatures are around 25c and load about 45c. i down powerd the fan to see how the heatsink would cope and after 30mins the cpu temperature had gone up to 69c which i didnt think was too bed without the fan running.
Would definately recommend as a basic heatsink and fan.
It's not perfect however, it needs a bit more thermal paste (I used Arctic MX-2) than most coolers due to the crude direct contact heatpipes, but what could you expect for £12?
I stuck this on my i5 6500, which was a breeze by the way, in about 40 seconds without even taking it out of the case, and threw my craptasitc intel stock cooler out of the window.
It's better than the stock cooler, and it's very quiet.
I ran Cinebench R15 five times in a row to test its performance in semi-real world situations and it aced it. The 6500 climbed to 65c and stayed there, with the fan speedo reading 1200 RPM, and hardly making a sound.
I didn't see any of the QC issues mentioned in other reviews, so maybe I was lucky?
Did I mention it's quite the looker?
Highly recommended. CPU temps are around the high 20's & double that when gaming. Very little to worry about and you save space in your case if , like me you have a smaller case body and the tall cooler's would limit you.
Dieser Kühler ist vielleicht nicht für die High END CPUs von Intel geeignet (140w TDP), kann aber durchaus CPUs bis 85 Watt TDP locker kühlen und bleibt dabei leise. Hinzu kommt auch noch, dass man diesen Kühler an alle gängigen Intel und AMD Boards anschließen kann. Adapter sind dafür vorhanden. Ich kann diesen Kühler für Gamer und Media PCs durchaus empfehlen für das Geld bekommt man derzeit nichts besseres.
Mein I3 4130T läuft jetzt nach einem röhrenden Boxed Lüfter angenehm flüsterleise bzw. gefühlt lautlos.
Während des Stresstests mit dem Intel Extreme Tuning Utility erreicht die Prozessortemperatur maximal 50° C.
Die Lüftereinstellung im BIOS ist dabei auf Silent eingestellt.
