I have an old PC with a knockoff LGA775 G41 mainboard and 4GB DDR3. The board only supports 1066MHz. Used to use Core 2 Duo CPU with no problems.
Recently, I got a used Core 2 Extreme QX6850 3.00 GHz processor from Aliexpress for $25. The processor works like a charm but the idle temps of all cores are 53 -55 ℃. During processor intensive tasks the temps hover above 70℃. Prime 95 gets it to 80℃. It doesn't go much beyond the low 80s.
I am not over clocking and the voltages and multipliers are at stock. Even downclocking the processor doesn't get temperature down by much. I use Arctic Silver 5 and reapplied it. Still no change.
I am using this HSF from my old CPU

My old core2 duo E7500 never went beyond 55℃ under full load with this HSF.
Is the Core 2 Extreme supposed to run this hot? Is it damaged from extensive use before I bought it used off Aliexpress? Or do I need a fancy HSF with heatpipes?
My cabinet is a full ATX with 2 fans and a 450W corsair PSU.
