I purchased an Akasa Venom CPU heatsink with yellow 120mm fan in 2010. My motherboard was an ASRock N68-UCC and my CPU was a Phenom 1055T running at Manufactureres clock - 2.8ghz with the overload ability disabled (boosts 3 cores to 3.3ghz temporarily)
Thermal paste was Arctic Silver 5 - having repaired a few xbox games consoles I used what I had left over!
Monitoring program was the ASRock software, "OC Tuner", the overclock tuner was perfect for giving the cpu clock little 1mhz nudges, but only being 16 I used it to monitor my CPU temperature.
1080p Gaming 38*C-42*C
Max Load 99.99% Stress Test 45*C-48*C
Motherboard (CASE) Temperature hovering around 28*C
My case is an NZXT M59 and I only had the stock fans, one exhaust, and one blue LED fan on the side window, the motherboard remained cool however.
I am 17 now so I apologise in advance for any mistakes in this thread!
Thankyou + I hope this helps you decide in a future investment with Akasa!
