7740x temps?

I'm just having a play with a 7740x I recently acquired, what sort of temps should I be seeing?

It seems to idle fine, room ambient is 29c, reported idle temp 33-35c which is in line with previous CPUs I've had.

I've given it a mild overclock on stock volts to 4.5ghz and using Realbench for stability checking it's reporting 88-90c on all cores(!) Is this just a reporting issue or legit temps? Presumably at these clocks and voltage it shouldn't be any hotter than a 7700k?

Cooler is a decent 240mm AIO, altering the performance curve of this makes near enough no difference.

I've reseated the cooler once and the TIM footprint looked fine and didn't make any difference to temps. I was hoping to have this up at 5ghz without too much trouble but not at this rate!

Any ideas? Motherboard is an ASRock X299 OC formula.
 
I would say so, temps vary from cpu to cpu depending on the contact between the Ihs and die which varies wildly
 
I don't think the 7740x was ever meant to be used on anything but Ln2 because it's only real point in existing is to run 7.2-7.3ghz at full pot and get 4 core global points in overclocking competitions.

Just run 1 time to make sure its not doa then delid XD

You shouldn't worry. Is EOL right now even just 10 months after it came out..... Go for it.
 
Temps are not inline with 7700k even at stock on this cpu as its on a larger package and 112w tdp which is significantly higher.

Delid is essential to run this cpu high. Once delided these cpu really fly.
