Simply the best. My HP laptop would get to the CPU throttling temp, of 100 C, within 5 minutes when I played games (diablo 3, starcraft 2). I took it apart (with help from the tech's dis-assembly manual), cleaned it up with https://www.amazon.com/gp/product/B00SJQFH7S/ref=cm_cr_ryp_prd_ttl_sol_5, and applied this thermal paste. Now, the temps stay below 80 C even when I play for several hours.
