I need to install the stock cooler back on my 2080 ti ftw3 ultra (currently have the hybrid kit installed) and need a thermal pad to replace the thermal putty that used to be on the vrms.
I asked evga and they said the thickness for the pad is 1.25mm. I am not sure where I can find 1.25mm pads so I was wondering if I can use 1mm or 1.5mm instead. What are you guys using?

    TF8 or MX-4 works very well on Both GPU and CPUs.
    No one can find good 1.25mm Thermal Pads anywhere.
    Some are saying that the 1.25mm Thermal Pads are too small.

    I bought 3 of these from ebay and they were here at the house when i got home. 1 of them alone will work on all the memory when you cut it to each die size instead of full strips.

    But sure if they are better then what we now have; I wonder what the  W/MK is on them.
    How is the Contact between the Block the Memory?
    Condition:Open box      :      Maybe even used not sure what this is really saying.

    They are brand new the ones i received, don't know if better then what we have because have not tried them. I was just showing that the 1.25mm can be found, i just got them to have so i can compare in the future if i need to take my block back off.

    Is it thermal paste safe? That would be easier because I have plenty. I was just going off the response from evga. I assume they would rather me use pads over paste.

    I have not used them yet, i just wanted to get some now while i don't need them instead of needing them and can't find anything. They seem to be of pretty good quality though.

    Replacing the thermal putty that was used over the vrms on 2080 ti ftw3 ultra. I cleaned that off when I removed the stock cooler and installed the hybrid kit. Now I need something to use in its place.

    If you could use pads, I'd go with the pads over paste since I feel that will make a mess and my OCD says heck to the no, no!  Just my personal preference.

    Agreed. It was hard enough to clean all the putty off the fist time.

    Pads over Paste on what?


    I have to chuckle reading the suggestion to use thermal paste instead of thermal putty, and then right after ask “pads over paste on what?”

    I have misread so many things and had to go back to see what I had missed.

    Still not sure why the thermal putty was used on the VRM versus the thermal pads. Maybe it had better heat transfer than a pad?

    The thermal rating on the pads has shown to be less honest than what most assume, from what I have been reading lately. I guess the company can use their own specific testing methods to make their product look better. I noticed that people (to include myself) have purchased the “extreme 17w/mk fujipoly thermal pads” just to find out they perform almost exactly the same as the 5w/mk pads because all of the other surfaces become limiting factors.

    Anyway, keep everyone updated as you try out the pads you found. I have become fond of the softer pads that are rated at 7w/mk just because they are easier to compress and don’t cause the pcb to flex like the stiffer pads can cause.

    I agree about the softer pads, but as far as the fujipoly i seem to get better thermals by using them, but not so sure its worth the money difference in the cost of them however.

    Well the eBay ones are going to take a while to be here (Aug 15 – Sep 26). I would like to try other pads for now.
    Thanks for your input on the softer pads. What thickness did you use?

    Am I correct in assuming that the next best choice is 1mm thickness since I can't find 1.25mm?

    The 1.0mm is what i used on the memory modules but then i also used thermal paste on it to help with the difference in the 1.0 and 1.25mm pads.

    Ha, that's exactly what I was thinking of doing.

    Hope it's OK to necro this thread!
     
    I am just waiting for my 2080TI FTW3 to arrive and I wanted to re-paste it but had a couple of questions.
     
    1. Is the advice against liquid metal TIM on the GPU die purely because you have to be extremely careful when applying it?  Or is there more to it?
     
    2. For the thermal pads, I have read though the above debate about 1.25mm being hard to get and maybe using 1.0mm with paste...  I was thinking why not use 1.5mm and just be sensible about how you tension the cooler down after?  I feel like if you replace all the pads with the same thickness you should be ok...  Or again is there a finer point I will miss until I have it in bits :-)
     
    Just for the reference, I am a veteran PC builder of ~25 years.  Done custom loops and things in the past, but always like to mine for insight before diving in :-)
     
    Thanks

    I recently did three overhauls on a 1060, 1070, and 2070 cards, in part using these thermal pads from Amazon, with pretty good results:
    https://www.amazon.com/100x100x1-5mm-Aikenuo-Conductivity-Conductive-Temperature/dp/B075JDF6JV/ref=sr_1_7?keywords=thermal+pads&qid=1571348799&sr=8-7
    Used these pads (which you can easily cut to fit) when rebuilding a PS4, as well. Results significantly better than the OEM pads (which covered only a quarter of the memory chip surfaces).
    Pads are advertised to give a thermal conductivity rating of 6 W/mk.

    I am just waiting for my 2080TI FTW3 to arrive and I wanted to re-paste it but had a couple of questions.

    1) Damage to the GPU / card Voids the warranty   Yes, there are steps & sometimes LM migrates & sometimes it dissolves wave soldered joints For a daily driver ... why risk it ?  Hey, want to chase World Records - OK thats 1 reason
     
    2) I would never use thermal pads & paste - for "gap filling" ... proper thermal pad heat transfer Requires some compression.  1.5mm pads would be the ticket

    1. Liquid metal is conductive and if it spills over off the GPU as TIM sometimes does, zap/poof!
     
    2. Going with a bigger size could increase the gap between the cooling base and silicon so you'll have to be careful on which pad size you use.  There are some that have experimented with this and found a happy medium. 
     
    I also agree that I would not recommend using TIM outside of the GPU processor because it will just create a silly mess. Pads are best used for that.

    Since very recently installing an EKWB GPU waterblock for the 2080 Ti FTW3 I found the thermal pads EVGA used on the stock cooler to be way thicker than the ones EK supplied. I'm not sure if that is by design for that particular cooler or not but you may be able to use thinner thermal pads and maybe get better cooling? I'll post some links.

    "Dry assembly" (no TIM) & checking Pad contact pattern is an important part of thermal pad installation checks

    I disagree with using taller pads. You then have the potential for increasing the height of the coldplate over the GPU die. The best thing would be to get 1.25mm pads, second best 1.0 with paste. Memory cooling isn't all that critical anyway as the max temp is around 90c. 
     
    I don't know why non-conductive TIM is a problem outside of the die area. You can clean it with a soft bristle brush and some isopropanol alcohol easily. Some LN2 guys have been know to wash off petroleum jelly in a dishwasher, so there's always that.

    The problem with doing this is that EK uses different height standoffs.

    So what is the general consensus?  1mm or 1.5mm to replace the thermal putty?

    Those silicone thermal pads are poor performing and did not last long at ll.

    When I replaced mine, I used 1.00mm thermal pads from amazon (ARCTIC Thermal Pad 145 x 145 x 1.0 mm).
    But I'll admit that I didn't realize they were 1.25mm until just now. I didn't notice and issues with the thinner size.

    I forgot to mention that i also used a bit of thermal paste too on the 1.00mm pads I used.
