Ferrari themed mod cont. 4070s repaste

[jallenlabs]

So my Asus Dual RTX 4070 Super was typically running at 80c with a hotspot of 98.5c using stock settings while gaming. When I purchased it new on release, it was much cooler. Id have to dig into my notes to find the temps, but they were never this high. So of course, I took it apart to investigate. The past had cooked and was pretty much non existant. The pads all looked good, but there were pads covering empty vram and vr spaces. Got rid of those and covered just the necessary places. I used Thermal Grizzly Kryonaut paste on the chip.

Now I had to choose, either put the old shroud back on, or slap some 100/92/80mm fans in its place. Although I wish I had tested with the shroud back in place BEFORE I reinstalled it with the replacement fans, I skipped that step.
I used a 92mm BeQuiet fan pushing air into the heatsink and a 80mm Arctic fan pulling air through the heatsink.

Testing. 3 runs each
Stock Settings
1- 3DMark, Stl Nmd 59/66/69c
2- 3DMark, Prt Ryl 64/72/75c
3- CODMW III MP 63/72/74c

OC Settings: Pwr Lmt 110, Temp Lmt 82, Gpu +155, Vram +255
1- CODMW III MP x3 consecutive, different levels 63/73/75c

Thoughts on results...
Sure, a repad and paste would have been sufficient as the cooler on the gpu is decent, but the fans are LOUD at 80% (what I typically had to run them at), so I think the de shroud and new fans will work out nicely. Now I can push the card harder, without as much throttling. I do plan to purchase two Thermalright 92mm x 15mm fans to replace the ones used in testing. Ill post back results if anyone is interested.

My understanding is that having a shroud and a small gap between the fans and the heatsinks make a measurable differece since it allows air to flow through the full heatsink rather than just the donut-shaped zones under the fan rotors. If you're changing the 25mm fans for 15mm ones, do a quick test with a cardboard shroud that uses the extra 10mm to space the fans away from the heatsink. If it works better than the 15mm fans directly touching the heatsink then you know it's worth your time to make something more permanent, either plastic sheeting and scissors, or get something 3D-printed

What's the little thing with a waterblock above the GPU in your photos? That waterblock's inlet fitting sure is in an inconvenient place for your GPU cooler!

Good thinking. I have spacers. Ill try the 15mm fans with them and without and against the fans that are there now. The card with the h20 block above it is one of the Optane drives. When I designed the cooling, I had the stock gpu in mind. Thats okay, I felt the need to tinker anyway. I could, I think, move the Optane blocks fitting to the top...

I overclocked the gpu to 2955mhz and the vram to 12000 (theres more in the vram I believe). Played MWIII hc mp for a few matches, reran 3dmark and got max temps of 66c on the gpu, 70c on the vram and 78c on the hotspot. Not too shabby. Well see what king of shroud I can come up with for the 15mm Fans I ordered (arriving Friday). ATM, Im stuck with a b660 board with no blck oc chip, so stock 12600kf clocks, but OC ring and memory.

BTW. I gained 10fps avg, 8fps low 5th and 3fps on low 1st in COD mp.

And with the new, thinner Thermalright fans. Temps went down another 10c with them at 12v (2700rpms).
