I searched for Graphene coating online to see what other professional applications it has. It seems it does help transfer the heat and some are saying "4x" increase in heat transfer. However, CPU radiators are transferring the heat to the air while the professional applications are usually for condensors which are absorbing heat from water/steam. So that seems a bit like the opposite...
It seems graphene might be more useful as a replacement for TIM (ARE YOU READING THIS INTEL???)
I'll order one of his graphene heat sinks today and hopefully see how it works this week.
thread over at chiphell had a new comment from OP:
tested in a... 银河W1 cylinder case (what company's 银河?) using Prime95 on an i7 7700K @ 4.5Ghz
Noctua L9x65
- 46C idle (22.1C ambient)
- 73C full load (22.2C ambient)
Cryorig Copper C7
- 42C idle (22.6C ambient)
- 72C full load (22.6C ambient)
The W1 is another startup case on taobao kind of like the Mac Pro trashcan. I think 银河 means Silver River or Galaxy, maybe someone with better Chinese can tell.
1C improvement seems like it's a waste of time. I was talking with KMPKT about this a few months ago and we were both expecting the Cu C7 won't offer much improvement if any at all. Might be why it's taking so long to reach the market, as marketing has to find a way to spin it and show more improvement than it really is.
