Well I left it to sit for 15-20 minutes and fully charge the battery, and now it runs at 3ghz again when loaded with cinebench
Edit: So my theory is that what maybe happened when I loaded it with cinebench, furmark and crystal disk mark is that it exceeded the 65W supplied by the AC adapter (cpu was set to 30W, gpu is also 30W and 970 evo plus is 10W), so maybe it sucked a bit of additional power from the battery?! but then that reduced its capacity bellow 100% and then it tried to charge it, that needed additional power, so it throttled everything else while trying to do that. Just a theory.

It's a good 'consumer' Thinkpad with 3 year warranty and good keyboard. Not much to complain, go for it.
