im pretty sure that is a socket a clip, not all heatsinks will work with it though,
have to have one thats got some of the fins out of the middle. if i find a pic ill post it
ok..tried installing it but no go....the seller forgot to sell me the instructions that's why I have no way of installing it...should I bend the fins in the middle so it will fit? What's your opinion..again this is for the si-97a..
That's not an SI97a clip. Not the Socket A or Socket 939. (The 939 has a twist knob in the center.) The SI97a requires a very specific clip which has centering pins, to keep the heatsink in place.
I would email Thermalright support, and see if you can purchase just the clip by itself. There isn't any other clip that will fit the SI97a.
