It is directly impressed by the size, at least 3-4 times larger than the intel +! In short, there must be room to install it.
Warning for those who uses large RAM modules, you may lose 1 RAM slot.
For my part, I have Kingston HyperX Genesis (low profile) and no worries. The fan comes just above my 1st slot with my bar inside. But just nickel.
CPU temperature side:
Basic:
Intel: 32-35 ° and Zalman: 20-24 °
During Benchmark (Fire Strike Extreme)
Intel: 65-70 ° and Zalman: 28-32 °
Either: +/- 10 ° under normal use and +/- 35 ° less during the Benchmark!
I specify that the fan is set to its silent profile: max 1500 rpm. And we never hear!
Temperature measured with AI Suite II
Pc tower cases used: Helios Prophecy (7 fans)
In short, if your turn is large enough to buy eyes closed !!!
