![]() ![]() The two tabs pushing the CPU into the socket when it's locked down actually bend the whole middle of the IHS (the hottest part of the CPU) away from the cooler, increasing the gap the TIM has to fill and reducing effective mounting pressure, which is why stock ILM thermal performance sucks, relatively speaking. ![]() You can also see the issue with the stock Intel retention mechanism in the pressure tests. The installation method shown is a good one, but honestly, you can be less precise.as long as you get pressure mostly even across the screws on the way down and don't over tighten things, you'll be fine. In this regard, Thermalright is actually going to be superior for most people as you get meaningful manual feedback without having to precisely measure torque, with no risk of crushing the socket. One difference that did stand out was the mention that the TG frame doesn't actually contact the board, while the Thermalright frame does. It's such a niche thing that it's a step that would come after trimming off any excess lead length from the DIMM slot through-holes (which can start to act as antennae at the I/O frequencies modern DRAM can reach) and shielding the back of the board with kapton tape and foil to reduce EMI. So, if you aren't running carefully hand binned parts in a near laboratory-precise extreme OCing scenario, one is going to be hard pressed to see any difference that couldn't be accounted for simply by adjusting screw torque on either frame. ![]() With regards to TG's claim regarding potentially superior memory overclocking.there are probably less than one-hundred people on the planet that could reliably quantify a difference as trivial as small variances on LGA pin clamping force (I've been OCing memory for almost 30 years and I'm not one of them). I was aware of Thermal Grizzly's claims with regard to tight manufacturing tolerances, and the lack of any specs from Thermalright in this area, but Thermalright isn't so sloppy that it would be meaningful (that ~240 micron variance GN measured on Thermalright's frames is already smaller than the tolerances on the socket itself). My earlier recommendation was going almost completely off the price differential, with the knowledge that Thermal Grizzly stuff, while usually nice, is needlessly expensive. ![]()
