These Temps Don't Look Right to Me

    So this is what I found while overclocking a 2700X to 4.2GHz/3600MHz on an ASUS ROG Strix B450-I Gaming motherboard. Worth mentioning is that I was not having any stability problems with the board, the temperature just did not look right so after checking my cooling loop, I thought I needed to check the TIM footprint. Well, there's your problem.

    Worth mentioning is that I keep a series of different water blocks on pigtail leads with Koolance quick disconnect fittings so I can move whatever platform to either of the cooling systems I use here to test with. When I disconnect a block from the system, I put painters tape over the coldplate so it does not get scratched up while not attached to a system.

    :) I did that once awhile ago with my 4770k and a hyper 212 with the plastic thing that says please remove before use :)

    I believe the CPU was at 80c in bios :eek:

    the spread on the tape is impressive. good hold-downs/mating on that one eh?!

    I thought the same exact thing about the TIM spread. That said, I do not stay inside the mfg suggested torque spec on my hold-downs either. You can tighten the hell out of all these AM4 and TR4 sockets nowadays, the more the better. I use some nylon washers between the block and the thumbscrews.

    Look at the bright side!

    You kept all that nasty TIM off the cool plate.

    I have to say that is not one of the many goofups that I ever had. Just about everything else, but not that.

    Well I will start wrapping the tape 90 degrees to that an over one of the edges from now on to make sure I do not do it again.

    It only made about a 10C difference amazingly enough under Prime95 load.

    "Thermal adhesive," I guess!

    I really like the idea of using painter's tape to protect blocks though, might just start doing that myself.

    That in itself is pretty eye popping. I am guessing the extra "hill filling" from the TIM was helping to minimize the insulating factor of that painters tape - the glue of the tape gets rid of air pockets on the other side. That's about all I can come up with to explain the minimal heat conductivity penalty.

    I do something similar but with plastic packaging tape. I doubt My results would be a good as Kyle's in this case. :D *heads to Home Depot for some 2" painters tape*

    I did that once. Back in the day they used to put clear tape over the cold plate and I got distracted and forgot to pull it off. The bad thing is I took the HSF off and thought I just needed to reseat it and did it two more times before I noticed the clear tape.

    Similar experience when I delidded my first 8700k, used the 1150 copper top replacement on the first one I did. You can't tell these apart from the proper 1151 versions just by eyeballing, but there is enough of a gap difference it really matters. The warning on the rockit website is no joke.

    Boot up to bios first time to adjust settings, on the asus fancy z370 board: "Hmm fans still at 100% after the first second? whats the te BIG NUMBERS IN RED OH FUCK".

    After I yanked the plug and pulled it back apart the liquid metal on the cpu didn't even leave a hint of a mark on the copper, it was not touching at all. Just that tiny little puddle was keeping it alive.

    Someone says "You can't overclock and run a cpu with painters tape as a TIM"
    Kyle_Bennett says "Challenge accepted, hold my beer."

    Really though, that is impressive that the cpu ran fine just hotter.

    Nice. I have probably left plastic protectors on the bottom of waterblocks and various coolers more times than I'd like to admit leading to similar experiences. :D

    It seems you now have obligated yourself to seeing how well it cools with just the tape without the CPU goo.

    Kraft singles and mayonnaise may have met their match!

    That Prolimatech PK-1 is no joke. Also, I bolt down those coldplates well beyond mfg spec, and I am sure that has something to do with it as well.

    So many people want to pretend like they never fuck up. Cheers for coming clean and submitting yourself for humiliation :)

    Its difficult to pick from my list.... Its long! I'd say one of the good ones was when I dropped a heatsink on a 6800nu years back, chipped off a cap on the backside of the card. I fixed it, but still.

    I once fried a 1TB seagate when I plugged in a molex that I mis-wired for whatever reason (messing with a fan at 7v I think).

    The damage to my car, well I wont go into details, but take my advice on this one: if you absolutely have to get someone fired, make sure you park somewhere on-camera that day.

    I'll see that and raise you when I used a cordless drill to remove the HSF off a $900 Intel Pentium III Coppermine Slot 1 cartridge. It died when the drill slipped :eek:

    Afterward I found out you could use a hollowed ballpoint stick pen to compress the little expanding tabs holding the fan shroud to the cartridge back plate. I still have the CPU with its ruined multi-layer substrate to remind me to always do my research first hanging on my "Wall of Shame".:(

    I always learn something from you gentlemen.

    How tight do you need to get the cooling block on the CPU?

    When building my first, and hottest, 8700k, I was really nervous about overtightening the screws and stripping a thread.

    So probably not as tight as I could get.


    Is it worth a few degrees to crank down the mounting screws?

    crank 'em down till you hear a crunch. ;) a good hand tight, maybe an extra bit. kyle says he cranks em down hard.

    Damn near impossible to over-tighten those Intel CPUs. Go for it.

    I'm really uncomfortable with the "screws only - no springs - no nuthin' " hold down solution Bykski uses. I hate lifting my 80lb PC onto my desk every week or so to make sure they are not backing out. I really don't want to use Locktite on them. So I'm oldskooling it and making my own. I think I can get something set up that would be a lot more trustworthy than Bykski's mount setup.

    Uh....OK. I think maybe you could check every 6 months if it is really bothering you.

    LOL.

    Thanks for sharing. Glad to see even a pro can make a goof.

    There will be more goofs for sure. Just this one was pretty funny and made for a good picture.

    Look at the bright side! You're ready to paint some accents on the CPU plate!

    Eh, those temps don't look right to me, either.

    Maybe we can get a consensus here?

    I think that means blue painter's tape outperforms most thermal pads...food for thought.

    It certainly saves time on clean up.
