Fan und reboot issue after sleep

Hello,

since a few days (unfortunately I  can't tell whether it was after some updates or what updates), my laptop has some problems with sleep mode.
I close the lid suspending the laptop like usual. When I reopen it, everthing seems to be fine for the first second. Then the fan spins up to maximum (even during heavy usage it never even came close to this speed). Another few seconds later the laptop turns of (no clean shutdown) and reboots. It seems I can use the laptop normally during this short time. The filesystem is always slightly corrupted afterwards.

I couldn't find anything related in the journal and have no clue where to look.
sensors doesn't show high temperatures.

Here is a short part of the journal around the reboot time:

Feb 28 01:19:35 Name systemd[1]: Reached target Sleep.
Feb 28 01:19:35 Name systemd[1]: Starting Suspend...
Feb 28 01:19:35 Name systemd-sleep[3861]: Suspending system...
Feb 28 01:19:35 Name wpa_supplicant[621]: nl80211: deinit ifname=wlp5s0 disabled_11b_rates=0
Feb 28 09:56:11 Name kernel: PM: Syncing filesystems ... done.
Feb 28 09:56:11 Name kernel: PM: Preparing system for sleep (mem)
Feb 28 09:56:11 Name kernel: Freezing user space processes ... (elapsed 0.001 seconds) done.
-- Reboot --
Feb 28 09:57:05 localhost kernel: Linux version 4.9.11-1-ARCH

1:19 is the time where i closed the lid.
9:56 is the time i reopened the lid. I don't understand why there are only 3 lines in the journal and why they are talking about sleeping.
9:57 is the time of the reboot (fsck  fails -> I manually run it to fix problems -> reboot -> everything is fine again)

Any ideas  on the problemor ideas how I can  further investigate this?

Thanks in advance
