Silverstone Tek Argon Series CPU Cooler with 120mm Cooling Fan

This proved to be an excellent CPU cooling option for my PC. Using an older mid-tower chassis with an Intel I7-377k (not overclocked), running a single exhaust fan in the back (92x92mm), 16GB RAM and a video card. The ambient temperature is about 32 °C, being in the tropics. With the stock Intel heat sink and fan, the temperature of the CPU was about 14 °C above ambient, in the range of 44 to 46 °C without any load. Using Skype or any VOIP applications will push the temperatures closer to 60 °C.After replacing the stock Intel cooler with the AR02 in May2014, the CPU temperature when idle is about 8 °C above ambient at 34 to 36 °C. At similar loads as above, the temperature rarely goes about 42 -44 °C, even with a single 92x92mm exhaust.Subsequently, added two intake fans (two Cougar Vortex 120mm) and replaced the rear fan with a Noctua 92mm to improve the air flow. Added a few Silverstone Tek 120mm Ultra fine fan filters to reduce the dust intake as well. I bought one from here, but the rest from ebay. But are even cheaper from the external store website of the ebay seller. Discovered it only after buying from ebay.Installation itself was easy, having upgraded the motherboard and processor about an year ago, the previous experience helped with the task. Had to remove the existing CPU air intake duct from the chassis. As mentioned in the other reviews here and elsewhere, the instructions need a magnifier to read. The video on the manufacturer's website helps a bit. The holes on the rear bracket not always match. Just match one or two holes and go with whatever hole that coordinates well while looking from the front of the motherboard. Keeping the chassis flat on its side is a must for installing this as with any CPU heat sinks. Positioned the heat sink so that the fan is blowing from front to the back and the air flow is vented by the rear fan. Both fans are almost in a straight line to facilitate this. The full assembly took about 30 minutes with all components ready and also using a magnifier to study the little diagrams on the instruction sheet.As mentioned in questions and answers, the heat sink projects 138mm from the motherboard surface. Still leaves about an inch inside my chassis. Did not have any issues with overhang over the RAM as I have two 8 GB modules with the other two slots empty.Did some research on positioning of the heat sink itself, especially of the heat pipes. My installation has the heat pipes in a sideways U configuration with the U lying on its left side. With sintered heat pipes (most of this type of heat sinks have sintered heat pipes), the positioning of the heat pipes, except for upside down, with the ends pointing down, does not matter.Hope this helps.Update on 13-April-2015:The PC is still going strong. Upgraded to a home grown wooden PC case, to improve the air flow, with better cable management and 3 120mm fans for intake and one 120mm fan for exhaust. The CPU temperature is 1 to 2 °C above ambient (tropical climate) without load. With load, spikes to 7 to 8 °C above ambient and comes down to aforementioned temperatures quickly.

A. Better than stock cooler, *with a replaceable fan*. Since there're many quality 92mm PWM fans available (Noctua is my preference) I feel confident, knowing that in future I won't have to remove the heatsink (and replace thermal compoud) if the supplied SilverStone fan starts to produce noises. Most of those stock fans, let's be real, aren't exactly "quality". Given that, fan replaceability is a BIG extra which you don't usually find at such low priced solutions.B. Installing the fan with the supplied rubber is extremely easy, and the most smart anti-vibration solution I've ever seen in a CPU cooler. SilverStone were creative here.C. Installing the heatsink itself is not difficult. Be sure not to install the M3.5 mounts instead of the M3 mounts (most of us need M3), otherwise you're gonna need a plier to pull them off (doesn't come off easily). It's confusing as they look quite the same but they are NOT. Watch the youtube video to understand better how to install without reading the instructions.D. Once installed, be sure to check BIOS for reasonable temprature. At first I didn't fasten the final screws tight enough (I used my fingers only), so the temprature was high. But once I did fasten tightly with screwdriver temprature decreased to half (Core Duo 2 E8500 3.16GHz now at 31c idle).There is no substitute to fastening the heatsink with a screwdriver, don't attempt to just use your hands.E. Temps dropped by 15c average, very happy. I'm actually think about buying 2 more as backup for my family.F. RAM blocking is a major issue with most tower solutions. This one doesn't block any of your sticks (even the closest). That's a deal breaker with Scythe's \ Thermalteke's currently offered solutions.G. Other current offerings for 92mm tower are lame: Arctic has many models but without replacable fans. However, you pay at least extra 10$ for a heatsink with replacable fan, so.. I don't know, everyone should do their math and decide. Antec also has a C40 cooler which's not currently sold in the US, but seem very similar to the silverstone AR02.H. Heatsink can accomodate an *attidional* fan.Conclusion: 92mm tower heatsinks market is lame, so there aren't much other options. I think this is truely the best option you have for a MicroATX chasis.
