    A toothbrush and iso works great for cleaning pad or putty residue.
    Just curious, what was the purpose of the conformal coating?
    As a sidenote, I think it makes the data easier to read and compare when temps are shown as the delta over ambient. For measuring temps, I think it's best to let the card heatsoak and reach steady state, then reset HWinfo and let it monitor for a set amount of time (maybe 10-20 min), then use the average temps as your datapoints. It's easier to control for ambient over a shorter period of time. Also it would be interesting to see more 3D benchmarks, since the load is more varied and you should see higher hotspot temps. It may show more favor to PTM.

      Good point on resetting HWINFO after reaching steady thermals, and then wotching ambient for those ~20 minutes. You're likely right about delta being more representative of relative performance. I'll likely list that in another column.
      As for the Conformal Coating, I wanted to give the card a decent protective layer for dust/dirt/fluids/vibration for the life of the card. In this video it wasn't truly necessary, but I thought I would include it in the video anyways.
      I've also done this to my testbench card. This should prevent me from needing to use Kapton tape in most test applications and I'm hoping it will also make the card easier to clean between tests, as well as lower wear and tear. My test card has been re-padded/puttied quite a few times now.

  • @chrismurphy2769
    @chrismurphy2769 4 місяці тому +1

    Could you repeat the test with carbonaught pads vs carbonaught pads + good thermal paste.
    The reason being that the sheet does a good job of filling the gap when there isn't good and even contact, additionally the paste does a better job of mating the surfaces (fills more of the tiny pores) for increased thermal transfer.
    Would a carbonaught sheet perform better, if coated in thermal paste?
    Would it be better to just use extra thermal paste (when the surfaces are exceptionally non-flat) rather than using a space-filling thing like a sheet of carbonaught.
    For a specific example of a card that has this curious problem, take a look at a Radeon VII.
    Apparently the heatsink and the die of the Radeon VII don't have the best flatness, and additionally the heatsink doesn't get sufficiently close to the die either, even if you lapped the surfaces, there would be a large gap that, for example, liquid metal would be a poor use case for, because it's too thin. Gamers Nexus has 2 videos showing that the Radeon VII has poor surface contact with its cooler that you could check out. Apparently the manufacturers of the Radeon VIIs were aware of the larger gap size and they used a very thick (and sticky) graphite based pad to fill the gap.

    • @snarksdomain
      @snarksdomain  4 місяці тому +1

      Something like that may work for a Radeon VII. I went with just a sheet of Phase Change Material instead on the Radeon. It was 0.2mm thick and can melt and compress down as needed. It seems to have worked well. My temperatures were about 3 degree cooler than the stock sticky pad (which was fairly old).
      The Carbonaut pads would only work for a core application. It would be quite costly to make enough sandwich layers of carbonaut and paste for the VRAM.

    Great vid. Any tips on pulling off the film on the PTM 7950 pads after cut? It always tears when I do it, haven't managed to get such a clean pull as you. Also can you test some other thermal putty, Zezzio ZT-PY6 and CX-H1300 claimed to perform on par with U6 Pro (if you compare W/mK). The CX-H1300 is particularly interesting because it is about 5 USD for 50g, that being said U6 pro is 15 USD for 50g (I live in South East Asia so the shipping isn't as much).

    • @snarksdomain
      @snarksdomain  Рік тому +2

      For peeling the film I'm now using 2 of the supplied tape strips and attaching them to either side at a corner. Only 1 of the films will peel off during the first step.
      Then carefully positioning in place. Once in the correct place I go over it with a finger and firm pressure. You can shine a flashlight (phone or other) at an a gle and look for any larger bubbles and work those out if you can.
      Once you are satisfied with it you can try using that 2nd tape strip at the corner and carefully peeling it back. This last peel takes finess as the sheet is not firmly clinging to the CPU/GPE die. I've still been using precision slant tweezers to peel last film.
      Placing of the cooler on to the CPU will also take some precision.
      I'd probably recommend to remove GPU so that you have the space you need to use both hands. Motherboard or case should be lying flat so that you can carefully lower the cooler down onto it.
      Unlike thermal paste, you need to get it perfectly centered on first contact. With paste it's always easy enough to shimmy it around even after the cooler makes first contact. Woth phase change sheet it could tear apart a bit if you move/twist the cooler during this time.

  • @taiiat0

    it's always nice to see affirmations of your own general experiences - that adding Paste to Pads doesn't seem to make them worse.
    but uh, i mean, why **wouldn't** you use Paste smeared Thermal Pads longterm? it's not like this is a much worse scenario or something, the Paste on the Core gets hot, so it's basically the same scenario if you ask me. and if it's okay on the Core, then i don't see why it wouldn't be okay on the Memory or VRM or w/e.
    if anything in addition to compensating for ejected Oil and w/e, that extra film helps compensate for Thermal Pads that are already 'used' tending to compress down and potentially being a little on the short side, making for less ideal contact. yet is still a tiny amount of added thickness, and so should avoid lifting the Cooler away from the Core.
    obviously using Putty and Pads would be preferable, but i don't have any reason to expect Paste to be **bad** in some way.

    • @snarksdomain
      @snarksdomain  Рік тому

      It's possible I've been too hard on thermal paste usage on VRAM. I might prefer not to use it myself, but perhaps it's not as bad as I had considered it to be.
      I've encountered a couple posts here and there in cases where thermal paste damaged components, but it's likely that electrically conductive paste was used in all of those occurances (ie. Arctic Silver 5).
      Edit: I likely wouldn't buy thermal paste for this purpose myself. I'd opt for either putty or pads, even just based on price/volume. I'd also worry about stuff like pump out. I think putty is better suited as a heat conductive gap filler. As for CPU's and GPU cores, I think a phase change material like PTM7950 is better than thermal paste long term.

      He also used old stock pads with paste for testing so in his mind he might be rushing to get new pads. As for myself i fear too much about not having the perfect sized peplacement pads so the cooler sits higher from the core ( causing it to not cool properly). Thats why i choose buying same or slightly smaller sized pads and adding the paste to fill small difference ( economical reasons, i cant afford buying 2-3 different sets of pads just to find the perfect one))

      Very true. I should have clarified I meant for people to use caution with other solvents that are typically used in Ultrasonic tanks due to their non-flamable characteristics, as opposed to IPA. Some have used IPA with Uktrasonic cleaning, but I think the additional risk is not worth it unless you have proper controls in place (oxygen free atmosphere maybe?).
      It would actually be kinda cool to have a toolbox like chamber that the cleaner sits in, and flushing it with nitrogen prior to cleaning. With pure Nitrogen being 3% lighter than air you'd need a drain on the bottom to vent out all the air during the flush.

    Great video and a very bold approach as well! I'm about to do the first clean up on my pc and was aiming to replace the thermal pads in my GPU and to use it in my M2 also.
    After LOTS, LLLLLLOOOOTTTTSSSS of research, I reached this conclusion:
    1 it may sound obvious but, the MAIN thing for thermal conductivity to work is CONTACT, so yes, you can't replace pads with paste, because even if you put a thick enough amount of paste, you won't have CONDUCTION, you'll have CONVECTION, which is way worse than conduction.
    2 before messing with those, consider how efficient your card can dissipate heat, otherwise you may solve one problem but creates another much worse. See this video to understand - ua-cam.com/video/vdIIA57treo/v-deo.htmlfeature=shared - heat likes to go to the cooler place available, if it's not dispersed quick enough, he's going back in and to the cooler surroundings
    3 in the specific case of your video, I think that if you applied thermal paste only to the dissipator contact side of the thermal pad, maybe it would've worked better, because heat would start to go away from the pad much faster, and it would keep receiving and RETURNING heat at the same pace from the die contact side, probably keeping a cooler "relationship" in between.
    We have two ways to go from there, you need a pad with lower conductivity than the paste, to work as I said, or you could try to "match" the conductivity for the heat to move as fast as possible, of course, having a strong dissipation environment.
    I'll check the condition of the pads in my setup, if they're still good, I'll go ahead and apply a layer of paste to see what happens, because there is absolutely no problem in having both in contact for much time as needed, the materials are compatible, so I'll only have to redo it if it actually gets worse, not better.

      There are not so much tests and reviews about putty that are really complete and rich in data. I've seen only one so far that showed all the temperatures, the guy was using a pink putty from Aliexpress, and it shaved about 10cº from the temperatures, but sky rocketed the hotspot by 20cº up!

      @brupleal feel free to check out my test data charts located on the Google Drive link below (Test Chart Repository>VRAM TIM>ETCHASH).
      Putty compresses better than pads, so you have a better chance to have lower hotspot delta over core temps. That being said, there are some cards that have really convex GPU dies and those can be difficult to get lower hotspots temps (AMD cards lately). Nvidia cars can get 10-15 degree delta over core temps, AMD is closer to 15-20 if you're lucky.

      You will either want to use a traditional Thermal Pad, or like many of us now use, "Thermal Putty".
      Thermal Putty is designed to fill gaps like this and transfer the heat well. There are some great Thermal Putties available, and they often are as cheap or cheaper than Thermal pads. As an example, I recently spent ~$22 CAD redoing a 3070 and replaced all pads with the current best performing Thermal Putty. I used 44 grams.
