However, thermal pads conduct heat less effectively than a minimal amount of thermal grease." Grease works better than a thermal pad. And > plus, see the 2 links shown under "References". good reading. Regarding link 1: It recommends one or the other, depending on the particular CPU. Regarding link 2: "promising start. Just 3°С higher compared to results with thermal compound only. However, I could not make a screenshot of Linpack test pass. The temperature sharply increased and went over 100° in seconds which triggered CPU overheating function followed by an emergency PC shut down." "Later I realized that my feeling were right. I launched the system, entered BIOS setup and went strait to monitoring section and… saw CPU temperature reaching 95 ° C, 5 seconds after it, the computer shut down. I checked the pressing, turned the pads on the other side — now the pink side was facing the processor. I started the system and got similar results. Test failed." "... thick pads the temperature increased by 7°С" Above, it talked about combined thermal pads and grease, or just just thermal pads, alone. Increasing temperature means that the CPU is not being cooled properly (they're measuring the CPU temp, not the heatsink dissipation temp). -- tim@localhost ~]$ uname -rsvp Linux 3.19.5-100.fc20.i686 #1 SMP Mon Apr 20 20:28:39 UTC 2015 i686 All mail to my mailbox is automatically deleted, there is no point trying to privately email me, I will only read messages posted to the public lists.
