crucial p510 with a heatsink sitting under an RTX 5080

So i'm trying to build a new pc, after finally picking all the parts the dude that i'm buying it from told me that putting the crucial p510 with a heatsink in the b850 Aorus elite would be a bad idea because of the proximity to the very hot RTX 5080. I was under the impression it won't matter much, a few degree difference or so compered to the motherboard heatsink, but he kinda insisted. He recommended me to buy the same ssd without the heatsink and use the motherboard heatsink.

Thing is, the motherboard have a large metal plate that covers multiple M.2 SSD slots together and i already have another SSD (xs70 silicon power) with a heatsink i want to use. it have dram and buying something like this today would be crazy expensive so that's not an option.

I tried looking for another motherboard that have separate heatsink on the m.2 slots but my options are very limited unless i'm willing to pay way more money with no real benefits other then that.

Is he right? is he wrong? Does anyone have experience with an ssd with a heatsink in the m.2 slot just under a hot graphic card like the 5080?

I guess i can try removing the heatsink from the xs70 silicon power and put it under the motherboard shared heatsink, but besides voiding my warranty i read it's hard and quit risky to do on that specific ssd, so i'm trying to make sure he's right before doing something stupid.

Any help will be appreciated
