I have the Optimus full replacement pad coming... and I just started tinkering with pads and I noticed that on my HC block that the pressure on 2 of the pads is just non-existent.  And the lower memory bank was barely making contact.  I did a sloppy job distributing the paste into the wells.  I got some more thermal grizzly to redo the memory pockets.  Previously, when installed, the HC block performed at an equivalent level vs the hybrid which was disappointing...  I had some temperature problems in my old loop due to volume of fluid.. but that has now been greatly improved in a new system. but like TPS was saying above, setup is key.  I don't know the exact difference in pad pressure vs no pad pressure but it must make at least some decent difference
 
I am going to make super sure that I get good contact this time. I know yall wouldn't have made such a rookie mistake but I thought I'd share for anyone doing a conversion

The Kingpin Hydro Copper 
 
 
I have my 3090 Kingpin Hydro Copper setup like a BEAST!! I made this video last week, and my temps are even better now!

Setup is key for these blocks!! 



 
I ordered and Optimus Kingpin block. But now I am really wondering if it’ll be much better?  
 
I made this video last week, and I have since improved temps even further.

tps, are you still using the full backplate 3mm fujipoly pad from optimus?  I'm about to convert my KP back to HC when I get some fittings but I would like to baseline it as a hybrid with and without the pad replacement and then convert to hybrid.  any tips and tricks you can offer would be highly appreciated.
 
I'm guessing you removed the stock pads rather than cutting around them.  any pics of the full pad applied to the backplate?  thanks my man, enjoy the card.

 
From TPS' youtube description if anyone is still messing with backplate pads like me.  I didn't realize the youtube had more comments in the description that answered my Q.  I just got my pad from optimus... fingers crossed.
 
"This video is intended for maximum thermal ability of the RTX3090 Kingpin Hydro Copper. This Kingpin Hydro Copper is using the stock pre-installed thermal pads for the front which have a 13W/m.k thermal conductivity rating, and 50 shore scal hardness. I have installed a Fujipoly 3mm full coverage back/rear PCB thermal pad under the back plate. This thermal pad covers the entire surface underneath the backplate (This is the only thermal pad on the back). (It works very very well) You can get one from Optimus watercooling, order the FTW3/Strix model for $38 dollars, and just trim it up a little to fit your specific mode 3090."

I've got this card coming in.
I know some 3090 cards had that gimped power plug 3.
 
Is that still the case with the kingpin version? What is the max power limit bios out of the box?

How's the KP Optimus block? Compared to HC?

How's the KP Optimus block? Compared to HC?

Nobody can tell because the Optimus blocks has had several delays so far.  It will be another 2-3 weeks before the blocks ship if there are no more delays.  Of course, that's typical for Optimus.

Likely not compatible with KP, but the EK active backplate looks pretty cool and really like the terminal connection....

The subject matter is relevant.  In the end, the active backplate is king of keeping the backside cool and screwing around with pads and whatnot is the half step.  Pads only get you so far though .  I just spend almost as much as the active backplate in pads, kind of sad.


I'm really looking forward to seeing some Optimus blocks going out.  I'm a hair away from preordering it anyway.

What kind of memory (fbvdd) undervolts have you achieved through classified tool?
 
Is 1.2 volts stable with stock memory speeds?

The memory temps are very good. No doubt the triple rad helps.
 
But does EVGA use better thermal pads on the kingpin vs say the 3090 ftw3 air cooled version?

All hybrid's weak spot is the cooling plate --- new product coming next week sometime, new direct cooling for all EVGA 3080 and up cards.  These lower mem temps 22c under the most demanding loads.  On 3090 KP, changing nothing else this dropped mem tjunc temps by 10c (back left alone for the time being).  This is a beta, but you get the idea.  No thermal pads needed, uses thermal paste only.  Works on all evga cards as well as several other MGS. On 80 and 80 TI mem temps drop up to 28c, backplate solution results still 2 weeks out. ES product shown below. 

3090 KP New beta plate


KP ready for assembly

 
KP w/ new cooling plate alone 124mhs 82.8c avg - nothing done to back as of yet (completely stock outside of hybrid plate)


3080 XC3 Air for comparison -- stock w/ air plate alone installed


3080 XC3 Hybrid

This looks pretty promising, however I don't feel very comfortable spreading the paste on memory chips and the PCB boards, if there is a thermal pad version I'm all down for that...

I’ve seceded to tear apart my 3090 FTW3 hybrid and build a custom loop

Weird fan rattle from radiator fans. I've got my rad top mounted exhausting in a fractal define r6. The top vent has a dust filter so it is slightly restrictive.
 
When fan rpm is between 1100 -1200, I hear a rattle from one or all of the fans. If I lower below 1100 or higher than 1200, the rattle goes away. Also, when I remove the top vent air filter when fan is between 1100-1200, the rattle goes away.
 
Would I notice a difference in acoustics to temp ratio with ARCTIC P12 fans?

I use P12s and even at full power they're quiet.  Get rid of that dust filter -- there's zero reason to have a filter on exhaust.

Expecting my 3090 Kingpin Hybrid today, and came across this nice thread.  Rather than going through a whopping 43 pages... Figured i'd ask about the basics.  Do the pictures on the first couple of pages suffice?
 
Before going through the process of taking the card apart and reapplying new thermal padding, wanted to try some heatsinks above the memory modules first, possibly even a 120mm Noctua fan attached to the heatsinks.
 
Any recommendations heatsink wise?  Any Specific copper ones that are recommended?   Length, width, height, etc... 
 
I'm hoping my backplate comes with good contact to the PCB, if not I will re-pad it.
 
 Thanks!

I bought the full length thermal pad from Optimus but I have not installed yet, I have a hydro copper in the closet and for now on hold , cooling on my card has not been a problem. Even at +1100 ofset it's never seen 80c

I have the full length pad from Optimus installed on my KP HC.  Previously I had 3mm Gelid pads replacing the EVGA stock backplate pads that were torn up from mounting the HC block.  The Gelid and EVGA stock pads were about as good as the Optimus pad - for me. 
 
Gelid and Thermalright 3mm pads are a fairly expensive mod if you want to do full coverage on the backplate.  It will probably be close to $200.  The optimus pad is a relatively good deal @ $50ish - again no major performance improvement for me vs stock EVGA pads.
 
After installing the Optimus pad, I just stuck a 140mm NF-A14 fan in my case that blows on to the card backplate which is vertically mounted.  I live in a hot area and the performance is satisfactory.
