donta1979 Those wondering and wanting to see how good Honeywell PTM7950 pads are if you do not believe those of us who are using it, maybe you will believe Igor. Not over-hyped: Honeywell PTM7950 in a lab test and a real game changer for graphics cards | igor´sLAB (igorslab.de)
nice find, great details ![](https://forums.evga.com/upfiles/smiley/thumbup1.gif) (excerpt) "Where I see problems are with water coolers and water blocks, where there might not be a complete phase change, at least on the cooler side. But you need at least 55 to 60 degrees throughout the pad for a complete change of state. “Half-defrosted” pads are counterproductive and are even more prone to cracking. At least that’s what one of the OEMs has now confirmed to me. Everyone has to work out for themselves how to solve this properly. I wouldn’t use a pad on a water block, at least not a PCM,"
well I was chatting with Igor about it on FB once he posted it, and I do warn people you really do not want to do this with a block or super crazy low temps like Igor mentioned, stock cooler, or a loop that runs really warm or an AIO cooled card? yup.

I've ran an EK block on the old 4090 /W EK suck-pads and KPx, since Dec '22 and I don't have the Temp needed for PCM , even at max OC

Yeah that would be a bit painful to try and cure you can do it yet you will have to reduce fan and pump speeds to make it really heat up enough to cure properly.
