Overall Review: I was looking to lower the temps on my budget gaming rig. During stress tests, core temperatures would surpass 80 C. Although this would not be a problem during normal use, I wanted a lower maximum for peace of mind. A maximum clearance of 140 mm eliminated the option of using the trusted CM 212 evo/plus. For a mere $20, I decided to try the Deepcool Gammaxx 300. Mounting the cooler was troublesome. I would have preferred the security of mounting to a backplate on the motherboard (as with the CM 212 evo/plus). The push pins of the stock Intel cooler and Deepcool Gammaxx 300 do not fill me with confidence. Even with the push pins, I had to remove the motherboard to ensure I was not applying too much pressure and to ensure the pins were secure. The Deepcool Gammaxx 300 would get a perfect score from me if it mounted using a backplate. Hardware: I3-4160, MSI H81I (itx), Thermaltake Core V1 (itx) Software: Prime95 (v27.7, using 10 tests of large FFT), HWMonitor (v1.27) Ambient room temperature: 20 C Core temperature with stock Intel cooler: 25 C min, 81 C max, 56 C delta Core temperature with Deepcool Gammaxx 300: 25 C min, 63 C max, 38 C delta I realize that using an after-market cooler was not necessary. Still, if budget and heatsink height allowed, I would have bought the CM 212 evo/plus simply because of the mounting technique. However, at less than $20 and a height of only 135 mm, I am pleasantly surprised with the Deepcool Gammaxx 300 and very happy with my purchase.
