New Thermal Grizzly Duronaut looks pretty impressive in this review.

we're in summer now, so it makes sense the temps will have gone up a bit vs. earlier when the ambient temps would have been lower.

I'm taking into account that it's summer as well as I thought maybe that had something to with it.

But here's the funny thing I take the 9900X out that was running throttled back at 58 to 59C almost all the time and then my temps jump to 64C and then I put in my 9950X and it's running 100% stock bios setting's because they got set back to factory default setting's and then I ran Handbrake right away with no EXPO turned on then turned it on EXPO1 and no difference in temp's either and it ran at 67 to 68C,both cpu's were changed in an hour of running the test's.

What I find to believe if the thermal paste was fine how is it a un throttled 9950X is only running 3 to 4 degree's hotter then a throttled back 9900X.

I also forgot to mention this before and then thermal grizzly seemed like it had dried up a bit as well and I'm not sure what it should be like after being used for a bit.

Also your application matters. Too thick and you get an insulator, too thin and you don't get enough coverage.

With thermal paste's I'm very very fussy to make sure that a real that layer does not get applied,I always ensure that the layer is just thick enough to cover the IHS so you can't see threw the paste and that if it were any thinner you could see threw it.

I have always be very careful that way as to not use to much because I read about the using to much paste is a bad idea and can cause temp to up which makes sense.

I just completed the 9900X build for my niece and used the Thermalright Phantom Spirit 120 Evo and the paste that came with it. Ran Cinebench multi-core and the hottest core was 74 C, with the others between 65-73 C. That is with EXPO enabled to run the RAM at 6000 but no other changes from stock.

Just for comparison to what you are trying. I was pleased with that max temp and workload.

If you want to try messing around with your niece's bios just does this,lower the PPT TDC and EDC by 16%.

Then go into Curve Optimizer and you can try starting with a Negative 20 All Core,all your doing is reducing the amount of voltage that the cores can get,run Adia64 Extreme for 10 minutes and check off Stress CPU FPU and Cache.

From what pretty much every youtube video I seen by guys lowering the PPT and also said that almost every single AMD 9000 Series cpu can handle running a Negative 20 All Core and it's rare that you would have to run an all core at 10 or 15 and they said it's not unheard of just rare.

You may also be able to get to 25 or even close to 30,from what I also gathered from the video's 25 if possible for a lot and you have to have hit the silicon lottery to be able to run stable at 30.

With my 9950X it runs faster encoding stuff in Handbrake with my PPT being set with the numbers below and I have to try and work on Curve Optimizer a bit more as I just went with 20 right off that and it's stable,I was getting 1350 to 1440fps encoding speeds and with my tweaked bios setting's I'm getting 1500 to 1550fps setting and I think because it's not throttling.

PPT 162
TDC 120
EDC 180

You can try these number for your niece's 9900X if you want.

PPT 135
TDC100
EDC 150

And then just try with a 5 or 20 Negative All Core in Curve Optimizer.

Appreciate the input! I won't be messing with hers. She just needs stability, no muss no fuss :) Coming from a 2700X she's pretty pleased with it as is.
