Ok, I'll spare the rambling and try to get right into it with pics and data. Short version 7945HX gets Conductonaut Extreme, The GPU was to get a Kryosheet but the Gelid Extreme pads you see in the pics had to get swapped for U6 Pro because it appears the Gelids are no longer as soft as they used to be and I couldn't get it to mount correctly. I thought it was the Kyrosheet and removed it before realising it was the pads, so the GPU has PTM7950 instead. Here's some base numbers when Stressed by AIDA64. Either for the CPU and memory, or specifically the GPU. The GPU gets stressed, then I boot CP2077 and run the bench several times with no DLSS so maximum strain on the GPU and VRAM. All testing carried out with the GT500 on maximum and Performance mode with the Extreme setting in the BIOS.
CPU Temps and power draw are key here. Using a CO of -25
This one is the GPU and VRAM. I think it's +250 core and +850 memory.
The red stuff you can see is Thermal Grizzly Shield. Both Kyrosheet and Conductonaut Extreme are conductive, thus sensitive parts are protected. I did also run a bead of SYY 157 around the 7945HX's shroud I just forgot to take a picture.
Running the same stress tests again... got me these results.
CPU being the focus here, only running a CO -22 this time. The sustained power was higher and it settled into the previous tests maximum of 148w at around 90c with odd spikes to 95c.
This is the GPU and VRAM. Fresh PTM and some putty on the VRAM has made lovely gains with the temps here too.
As you can see the thermals are much better than stock here. I do plan on swapping the U6 pro for CX-H1300 and ordering fresh PTM 7958 SP for the GPU to see if any more gains are possible. With the 7945HX having so many SMDs exposed, I imagine they opted out of having to find a safe solution, I mean engineering samples had silicon globs on them, but doing that without them being higher than the die itself could be challenging. I opted for TG Shield, I think Lenovo could have done this and used a foam square on the inside edge of the shroud. Not doing it at all is cheaper. Still, I find giving the i9 liquid metal and ignoring the R9 despite advertising it.. it's a little despicable.
Bonus pic and I guess a few flexes if you like.
Snuck a Legendary in Time Spy. CO -20, RAM at 5600mhz CL38-38-38-38 then the stock PnP timings for 5600mhz everywhere else on the Fury Impacts and the FCLK tweaked to 2033mhz. GPU with +250 Core and +850 memory. Note, I do not daily the GPU OC)
Post overhaul CB with a CO -33. This is just a Bench brag, CO -33 is not generally stable and will crash if stress tested. But! Look at those temps and clocks ;) If Lenovo need a laptop BETA tester or external modder, email me 😛
So what do we think people?
