i decided to do an experiment and try to run an LLM in my old 2013 MBP. i7, 16 gb mem, 1 tb hd. Installed Linux mint Xfce Edition for lightness, installed ollama, start to test different models. Gemma4 e4b runs perfectly fine, exposed it to the network, connected to it with my current notebook and use vs code codex to start to run inference. For about 30 minutes of bliss, this setup work at a reasonable speed... then…

Could be in need of a thermal paste refresh etc.?

and redo the thermal paste

> On the other hand, my wife saw all this and offer to buy me an M5... Hold my beer. I'm going to run Qwen on this 3rd-generation iPod... somewhere my partner can see

i can sell you my MBP, but no refunds if it doesn't work

hahaha

On a laptop that old it might be worth opening it up to blow all the dust out with a compressor or air duster. I’ve often found that to work wonders on old MacBook Pros. The other issue is that unless the battery has been replaced relatively recently its charging efficiency may not be that great and the high load being placed on it might be causing it to get hotter than it would have done when new.

I have personally replaced the battery a couple of times already... but a good clean up is a good idea

Give the fans a really good going over: tend to find loads of dust and fluff hiding inside them.

Won't work on M processors, (un)fortunately.

TBH there was a shameful period when producers were "reinventing" QWERTY keyboard and had a better idea whether Ctrl key should be present and where it should be located. Remember when Apple removed the Esc key?

I had Windows and Mac laptops back then, and the HN snobbishness around the superiority of the Mac was genuinely baffling. My i9 2019 MBP with discrete graphics was probably the worst laptop purchase I ever made. Docking it to an external monitor would enable the GPU, so even when idling it would run the fans and drain the battery. I’d read cautionary tales about Windows laptops being pulled out of backpacks scorchin…

It was a truly ridiculous idea to put an i9 in any laptop. That generation of i9 is difficult to cool even with liquid cooler systems in big ATX cases.

Just to remind, the mobile + desktop lines are not the same thing even if they both get the same branding.

The top end chip in the 2019 MBP was the i9-9980HK, which had a TDP of 45W.

Would have been reasonable in a chunkier workstation/gaming type of laptop with the kinds of cooling solutions those usually get, it's not something that needed an actual desktop liquid cooling solution to run well.

But obviously the 2019 MBP design/cooling was not up to that task.

How does the Neo getting to 100°C make it crap? By that logic, aren't all older Intel/x86 chips crap? If anything, I find it impressive that a small laptop CPU can do 100°C without a problem...my i7-7700T M710qs hit 75°C and throttle within a minute if I use a tool like y-cruncher or stress-ng. To be fair, totally different purpose.

For a very long time now, it has been the case that in the short term most processors will boost high enough for the die to reach around 100°C. When you see a reading substantially lower than that like your example of 75°C, either the system has throttled for a reason other than processor die temperature (eg. throttling to limit the temperature of the outer case of the machine) or the temperature reading you're seein…

Curious about the T case - is Intel doing some kind of binning and trying to select the processors most likely to fail under high thermal load to assign that suffix to? And thus the T procs are priced lower?

Oh yeah, I forgot about the graphics. I had (and still have) a 4k external monitor. Naturally I wanted the MBP to drive the monitor with a resolution that took advantage of all the pixels. Unfortunately with most monitor settings the GPU power consumption would produce enough heat to run the fans even if the rest of the system was completely idle! If I set the output to full HD the GPU would cool down and the fans wo…

How could orientation and cabling affect heat??
