I would discuss these which are available for me and which proven to work (cool) very good, and these are : GELID Ultimate, GELID Extreme, Thermalright Odyssey 12.8 w/mk, Thermal Grizzly Minus 8 pad.
well, I don't understand some specs about mentioned pads hardness, softness, ability to compress, adjust..
all my knoweledge about it is based on expirience with using them, but I would like to know and understand real specs about that
I will give just one example, on 3070 TI, I replaced memory thermal pads with Thermalright Odyssey. Stock pads was 2mm (I really belive I measured correctly), and of course I used 2mm Thermalright Odyssey. However, due to fact Thermalright Odyssey is harder than stock ones, I run into another one problem. Obviously cooler was not able to make proper contact with gpu chip, leading to gpu core increased temperature (memory temperature with Thermalright Odyssey really improved hugely at same time), despite fact I used Thermal Grizzly Kryonaut paste on core (X pattern). Than I used better screws (stock ones are crap really), and some tricks to increase cooler pressure, which resulted in decrease of core temperature finally. I have 0% doubt, issue was with Thermalright Odyssey hardness (or whatever it is called).
so this would be very useful not only for me, but for many other users, to understand and get info about these thermal pads properties - it is not just replace and get better cooling (of course, you get way better cooling compared to stock ones, that is out of question), but you really need to pay attention, check every pad is making proper full contact, etc.
knowing and understanding these specs and properties would be very useful
yes, it is already known for example that Gelid Extreme is more "soft" compared to Ultimate. But I would like to understand matter more and get more specs.
now, what confuses me is this : Thermalright Odyssey for example clearly state (writen on product) Hardness as : (Sc)：30~55 . And density (g/cc) as 3.1
now take a look at Thermal Grizzly Minus 8 pad datasheet :
it states Hardness as "Shore 00" in value 60 (I did not found density value).
when you google about Gelid Extreme and Ultimate indeed you get Hardness stated in "00" value.
but why Thermalright Odyssey state Hardness in " (Sc) ", while others state it as "Shore 00" or "00". Does someone knows more about meaning of that?
And what about density? Does density value actually tell us also about how hard/soft/adjustable thermal pad is? Does density correlate directly to hardness or (Gelid Extreme density is lower as I found on internet, compare to Ultimate) ?
please, let us put some info and research into this, and provide at least some rought differences in specs. so all of use can know which pads is going to behave in which way under certain conditions, or better to say what we can expect when using some of them, compared to another one
looking forward to more info
tnx in advance!
