It's a real shame they continue to use the Intel push-pin mounting system.
I stopped selling Zipang to my clients and pretty much ceased Scythe coolers altogether for this reason.
Today I ordered a Mugen-2 cooler for an ESXi platform with a quad-core processor. SPCR gave the new cooler a glowing report, especially on the bolt-through mounting system sturdiness.
Hopefully Scythe will leave the push-pin silliness behind soon. This system bends the system boards, and is not acceptable for more than the Intel stock cooler.
