I had same problem because ASUS manage to not apply thermal paste correctly. Already ordered PTM7950 but kryonaut will be good for now.

I have the same issue with my TUF, I repaste and hotspot + core drop by a lot, but then 7-10 days later and temps go back up. I tried TM Kryo Extreme and Noctua NH-T2 and both didn't keep their initial temps. I'm waiting for 7950 to arrive to see if that helps.

Where is everyone ordering PTM7950 from?
 
Seems to be some quality issues or knockoff/counterfeit product out there, that some people have reported on other forum's posts
 
The results look very good for the PTM7950, I just want to get it from a reliable vendor

My friend ordered from this store on aliexpress preformance is phenomenal (he didnt have any left so i was forced to order). Only seller that actually sell original honeywell 7950.
You can remove link later if its against evga forum rules. Also moddiy sell those for US and they ship super fast and you dont need to wait 1+ month.

I can report my temps are still the same a month later. I ordered mine from here… https://www.amazon.com/gp...x_pop_mob_b_asin_title

I saw LTT was also advertising that they are now selling it because it was hard to get legitimate supply and they saw an opportunity to offer it on their own store.

 OK, I found that
LTT store PTM7950
https://www.lttstore.com/search?q=PTM7950&options%5Bprefix%5D=last
60mmx60mmx0.25mm @ $14.99 USD
200mmx160mmx0.25mm @ $69.99 USD
shipping looks to be $9.99 (for my address at least)
 
there is a place for discount codes - if you have one.  (My online automatic code checker, "Honey" - did not find an active discount code)

I'm hoping you keep updating your test drive, will be interesting to see a monthly update to see if it lasts 1 year or more
 (from Amz link above)
PTM7950 40x80x0.2mm @ 16.99
seeing an instant discount ($3.00) - (for now, Amazon "live pricing")
 
Thanks everyone

By any chance did you measure the H & W of die that touches the vapor chamber plate? I have looked and asked everywhere with no luck. Nvidia’s squared measurement is wrong as the chip is taller than it is wide.

Well just put the Honeywell pad on my Rog Strix oc 4090 hotspot was getting up to 82c, the pad an automatic drop with no cure time yet freshly installed it’s already down to 67c. Idle temps went from 28-31c down to 26c already.

MODDIY if you want an authentic one that performs better than some of the pre packaged knockoffs of Amazon. There are legit ones on Amazon but I wanted to ensure I got the real thing.
