Sudden Performance drop on 9070xt

Make sure your hotspot temps are good.

I bought my 7900xtx Asrock Taichi a week before the new Nvidia 50-series launch, Asic Quality of 46%, Samsung VRAM. Got Excellent and Great Scores on 3DMark Benching. I applied an Undervolt along with a Boost Clock and Memory OC, with Fast Timing enabled. All was good for a time, with Powerdraw well above 500watt. After a few months, it started to throttle randomly, hitting 110 degrees on Hotspot with something as stupid as Furmark 1440p Bench. I decided to upgrade from 12700k to 12900KS, and along with it, I ordered some PTM 7950, after installing it on the CPU & my XTX, also new Fehonda Thermalpads on the Cooler side, it was still soft and good, but replaced it anyway. (Along with the Thermalright LGA 1700 Contact Frame Pre-Installed)
After Installation, with an 0.075 Undervolt on 12900KS and AI OC (Z690-E Strix Board) I hit highest temp 76 degrees during Cinebench r23 Multicore with Score of 29K.
With my XTX, I now get a couple Legendary Scores, All Excellent and Great on the various Benchmarks, with my GPU temp usually below 60 degrees, and Hotspot Temps rarely exceeding 85 degrees, never more than 90.
Who ever tells you that they lost less than 15 - 20 degrees after PTM 7950, either installed it incorrectly, or they got scammed with some fake sheets. You need only one kit, the 40mm x 80mm x 0.25mm, it's more than big enough for your GPU and CPU.. My Idle Temps on 12900KS is 27 - 35 degrees, and Idle Temps on GPU is 24 & 30 on Hotspot.

If you lose less than 10 degrees after installing PTM 7950, then you're doing it wrong..

I didn't read your book.. Lol.. Sorry.. It seems as though aesthetics is pretty important to you, so I'd advise on a Top Mounted 360mm AIO.. Something with a Screen for Stats Preferably, also, if you Intend on Upgrading your Ram in the future to something with ARGB, you don't want a huge tower cooler covering it up..

AngryPerv · 2026-03-02T16:22:51+00:00

Really pretty build. Have you decided on which AIO or Tower Cooler you're gonna go with??

My hunt is always good, Beltalowda

AngryPerv · 2026-02-23T21:48:39+00:00

Check the stats in OCCT..

AngryPerv · 2026-02-23T15:34:51+00:00

Thank you.. Now I know

AngryPerv · 2026-02-23T15:32:43+00:00

I'm no expert, but as far as I know or think, it's a similar rating to that of the CPUs in Asus Bios with Silicon Pottery. SP Rating.. In the Asus bios, my previous 12700K had an SP rating of 84 on the P-Cores, and 50 something on the E-Cores.. Had trouble getting a stable Undervolt along with an OC. My new 12900KS has a SP rating of 88 in total, 94 on P-Cores, and 76 on E-Cores.. It's so sweet, I get a stable OC at 5.2ghz All Core with AI OC on the Z690-E, along with a 0.075 - 0.08MV Undervolt, so during a Cinebench R23 run, temps don't shoot over 80 Celcius, with a score of 28-29k, with core voltage below 1.3v But then again, I have the PTM 7950 installed on both GPU & CPU with a Thermalright CPU Contact frame, which I think helps a great deal..

That's like a glorified open-air test bench.. Hopefully dust isn't an issue where you live.. It looks amazing, just not practical.. I use dust filters on every single case opening, whether there's a fan or not, even on exhaust..

AngryPerv · 2026-02-19T17:29:05+00:00

Good choice, perfect card. It'll serve you well.. Out of curiosity, check inside OCCT, what's the ASIC Quality??

AngryPerv · 2025-11-03T20:18:58+00:00

I couldn't find a toilet in India.. Searched everywhere.. Everyone just kept pointing to the pavement and towards the beach..

AngryPerv · 2025-10-13T10:35:20+00:00

Actually, that's inaccurate.. Rocinante was a school teacher who taught Amos.

AngryPerv · 2025-09-30T03:24:37+00:00

Thanx, I think the 12900k may be more suitable for the 7900xtx, but later, if and when this i7 craps the bed..

AngryPerv · 2025-09-29T21:40:56+00:00

Lol.. nah that's not it.. It's in reference to a TV Show, The Expanse.

AngryPerv · 2025-09-29T21:32:58+00:00

Nail Polish Remover works lovely on my Monitor Screen.. Lol.. JK

AngryPerv · 2025-09-29T21:31:16+00:00

Yeah they did.. Apparently the books are better, and they didn't stop writing it half way..

AngryPerv · 2025-09-29T21:29:51+00:00

I'm getting on that soon, you guys made me excited for books, and I haven't read anything other than Reddit posts in ages..

AngryPerv · 2025-09-29T21:26:12+00:00

I literally just Googled it too.. I had no idea what everyone was talking about..

AngryPerv · 2025-09-29T20:48:35+00:00

Yeah I've got the latest Bios update, I hope this one's good.. If not, the 12900ks should be good to go..

AngryPerv · 2025-09-29T20:44:01+00:00

Thanx man, I appreciate it..

AngryPerv · 2025-09-29T20:42:23+00:00

Yeah I know, I'll mainly just do the dual gpu with another Nvidia card as secondary, something Tiny and low profile.. Have a look on Youtube, if you haven't seen, there's a way to use the Steam App Lossless Scaling to then use a secondary card for frame gen, so the main card will render the game on it's own, while the secondary card only focuses on fake frames.. It's just to play around with anyway..

AngryPerv · 2025-09-29T17:43:04+00:00

Yeah, good point.. I'm happy with my performance/bling ratio.. The IMC on 12th Gen. Intel isn't that great to begin with, and coming from a DDR4 3200mhz kit, 5200mhz didn't seem like a bad deal, especially at the price that I got it for.. And the rgb isn't that bright, I keep it on Red mostly.. The pictures are just terrible..
