OK, will ignore it, 88C to pretty normal for a higher end laptop gpu.
I wouldn't completely ignore it, but its not something to go crazy about it either, and let me explain
As mentioned this (GPU) Hotspot reading has usually a max operating limit of 110C.
A GPU has dozens of temp sensors across the silicon die and this particular value reports either the absolute highest one (which ever that may be on any time) or it reports an avg (aggregated) value of the most highest sensors among all of them. For example, the total count of sensors may be something like 50, 60 or even 100, and the report is maybe peaking the 10-20 highest of them (which ever those may be on any time), then makes an avg and send it out as a hotspot temp.
Its very normal (especially to gaming laptops) to see 110C on this reading occasionally and even an almost constant value of 109-110C
But...
Assuming that someone plays games often and after some of the gaming sessions.... opens the GPU-Z or HWiNFO logs (like you did) and observe what temp this hotspot usually has and what is the GPU clocks.
And after some substantial time period starting to see that Hotspot temp is always staying at 110C and GPU clocks are lower than usual.
This may indicate for example that the cooling slolution either needs cleaning or maybe is failing.
I understand that some times all this (new) info that we didnt have before can be overwhelming to a user, but I think of them as tools in my disposal to better know and understand the system's behavior and condition.
Something like this that always running in background
