--- Comment #13 from Uwe Michael Scheffer
(In reply to Uwe Michael Scheffer from comment #8)
I have a multi-bootable SSD with TW, Leap-15.4 (with 3 kernels to choose from) and Leap 15.3 systems on it. Leap 15.3 always goes to idle temp 45�C, Fan level 0, however, the TW and Leap-15.4 systems both show the 60�C idle temp issue. Installing 15.3 Kernels on a virginly installed Leap 15.4 system does not help with the 60�C idle temps. And remember you CAN see 45�C idle temps, fan level 0, too, on the latter systems, however, only erratically with a "mesasured" probabaility of ~ 25%. So, these are the current results. What do you make of them, what do you especially make of the stochastic behavior?
Did you try the SSD on an other ThinkPad? Given the shaky behaviour I would check whether it occurs on other hardware too.
Today, I tried with a different SSD (of exactly the same type) on a different ThinkPad W530 (same type, too) and got similar results, however not quite the same. Leap-15.4 neither on btrfs nor on ext4 would reach 45�C and the fan would never relax to level 0. So with Leap-15.4 there was always the 60�C idle temp issue. With Leap-15.3 there was a surprise, on this ThinkPad temperatures would cease to 45�C only in 50% in about 10 reboots, the other 50% temperatures would stay above 55�C near 60�C, fan would wander between level 1 and level 2, but never would cease to level 0. Here's a table showing the results of days of installations and runs. ## 60�C Idle Temperatures Issue on ThinkPad W530 --- Device (A) vs Device (B) Leap-15.3 vs Leap-15.4 SSD vs Live-System btrfs vs ext4 --- Thinkpad (A) -> Leap-15.4 -> SSD -> btrfs 60�C = 75% / 45�C = 25% Thinkpad (A) -> Leap-15.4 -> SSD -> ext4 60�C = 75% / 45�C = 25% Thinkpad (A) -> Leap-15.4 -> Live -> ext4 60�C = 0% / 45�C = 100% Thinkpad (A) -> Leap-15.3 -> SSD -> btrfs 60�C = 0% / 45�C = 100% Thinkpad (A) -> Leap-15.3 -> SSD -> ext4 N.E.
