i7 2670qm in T420

#1 Post by TPFanatic » Sat Sep 21, 2019 7:47 pm

I am building a Super T420 with quad core and the WQHD mod.


Step 1, the quad core an i7 2670qm, is arrived and installed.

With Prime95 stressing all four cores the Quad Core settles in with each core running at base clock (2.2 ghz) and temps hovering at 80C.

With Furmark stressing the HD3000 at the same time the temps rise to around 90C. Furmark framerate averages 6 FPS.

With Furmark on but Prime95 off the HD3000 takes up to 15W and Furmark framerate averages 9 FPS. Temps hover around 60C.


The machine will double as a gaming rig hooked up to a GTX 960 through Expresscard GDC Beast.

I have always thought about hooking up an external video card to my T520 extreme. But never followed through with it. Too many wires and not mobile enough.

I bought a new Dell G3 instead with the NVIDIA® GeForce® GTX 1660 Ti card installed. Runs very well with X-Plane 11 and the Boeing 727 add-on. Frame rates are hovering around 60.

Ordered an old Lite On MLC mSATA drive to replace my shoddy 1.8" SSD in 2.5" adapter currently occupying the main bay. My intention is to install Windows on the mSATA drive, along with essential program there, then put a 500GB spinner in the main bay serving as the storage drive for the video games.

The WQHD adapter is in the US and likely to arrive sooner than the LCD itself. Once in, I'll test it with the WQHD LCD out of the T430s. There will be pictures of the setup then.

Hi, I have t420 with i7 2670 and 16gb 1866hmz RAM and FHD IPS MOD and I am planning to upgrade it to WQHD. I am looking forward from hearing some new news about WQHD MOD. You will be probably among first who will do the mod working on t420 non-S.

The WQHD mod I got from e-qstore works great. I'm running it with the B140QAN01.1 out of my T430s for two reasons: First, the new WQHD I ordered from China is an incompatible LCD. :evil: Second I killed my T430s' Intel HD4000. :oops: How do I know the HD4000 is dead and not the NVS 5200m? I get pretty lines on the internal display but external displays show fine, and video out on these Optimus models always passes through the NVS 5200m. Surprisingly there is not option in the BIOS to use the NVS 5200m only. No idea why this was decontented. Older T410 with Optimus NVS 3100m 512mb had the option as do newer Optimus ThinkPads. For shame.

So the modkit works great as does the eGPU going to the internal display. 2560x1440 cleanly downscales to 1280x720, an appropriate videogame resolution.

I am having problems cooling the i7 2670qm, it can't sustain full-turbo or even normal-turbo and throttles hard when stressed. Granted, most desktop apps don't stress a CPU, but the idea is to use this for videogames where the turbo will make a difference. A T520 I built up with a 2760qm and dGPU heatsink does a much better job and sustains turbo thanks to the thicker CPU heatpipe on the dGPU heatsink, functional rear vent, and already massive side vent. I'm thinking of trying to fit a T420 dual heatpipe heatsink or a T430 heatsink in.

Many on the subreddit claim the 14" dGPU heatsinks cool the CPUs better than the 14" iGPU heatsinks, but this doesn't make sense as the CPU heatpipes are the same size on both versions. At least on the T430 heatsink, the two heatpipes touch eachother for most of their length, so maybe there is some help from the dGPU heatpipe there? However this doesn't fit perfectly in the T420 frame without mods, see what this redditor did.

Right now I'm running with turbo disabled and it's cool and quiet.
