I'm always looking for ways to improve CPU thermals. I have delided in the past and I'm not a big fan of it. I also don't really like the metal based TIM's due to inherent risk of electrical conductivity. I found some thermal pads with really high thermal conductivity, 17W/mK! Most silicone based TIMs, Arctic, IC Diamond, Noctua NT-H1 have a thermal conductivity of between 3 and 5W/mK. For comparison Cool Laboratory's Liquid PRO is ~40W/mK. So why are we not using these thermal pads? They're pretty expensive but apparently 3x higher conductivity than silicone based, and almost half that of liquid metal based TIMs. Has anyone tried high performance thermal pads for CPU cooling? 0.5mm thickness seems appropriate, and I doubt it would dry out and crumble any faster than silicone based TIM. Is it worth a try? Or does anyone have solid evidence to avoid this?
