Post subject: | Lower operating temps by high quality thermal compound |
Not a specific piece of hardware that I am recommending here but a method to lower operating temperatures in general. Fact: Lower running temps for CPU, GPU, RAM, etc. can be achieved through more effective contact between components and heatsinks. Fact: With few exceptions, the factory uses cheap thermal paste and often too much of it. Recommendation: remove the heatsink, clean the surfaces, apply a small amount of a high quality thermal paste like Arctic Silver 5, reseat and enjoy lower operating temps. Case #1: Passively cooled Nvidia GT520. Link to project pics Before with GPU idle temp: 56 C After with GPU idle temp: 48 C Difference: -8 C Case #2: Zotac A-U. This is probably not a perfect case because I actually added a small copper shim literally on top of the CPU to further increase the contact to the heat sink. Link to project pics Before (factory thermal pad) (Idle/Load) GPU: (33/35) MB: (28/32) CPU: (40/52) Core0: (43/54) Core1: (41/52) After GPU: (33/34) MB: (28/30) CPU: (36/40) Core0: (38/43) Core1: (36/41) Differences GPU: (0/-1) MB: (0/-2) CPU: (-4/-12) Core0: (-5/-11) Core1: (-5/-11) |
