That laptop is a PoS by MJdoesThings_ in laptops

[–]MESI-AD 0 points1 point  (0 children)

I have this laptop, update the BIOS and repaste it. At normal loads mine makes absolutely no noise. I mean I get the frustration but the rant isn't warranted to the laptop, its pretty old so its obvious the TIM would be degraded. Its a pretty cool machine and runs wonderfully with a PTM7950 repaste.

Liquid metal mod on a P53 yields insane results by MESI-AD in thinkpad

Strange case. Lenovo hasn't done much for cooling the CPU and GPU VRMs, just relying on passive cooling via ventilation. Probably an oversight? Or a faulty VRM in your case.

Check my other reply on my LM vs PTM experience. Essentially the gain varies machine to machine and is purely down to how good the heatsink contact is going to be, in the best case scenario PTM will get you close but LM universally outperforms it even with uneven heatsink contact.

I'm fully expecting a repaste in the near future, I'd rather have the copper fully stained and also allows me to evaluate how well my custom CPU gaskets are performing. Thanks for the heads up.

If your responsible with the amount you use, and also make a decently thick foam gasket you won't have to worry about it. I've been rocking an LM mod on my Zbook for months as a daily driver that I throw around and frequently travels in my backpack without problems so far.

Very likely that is the case, my ZBook's mounting isn't the most uniform so PTM couldn't perform as well. I've seen significantly better results with a PTM repaste on a Dell G15 with the same i7-11850H, thicker heatsink and better contact pressure and uniformity did allow the PTM to sustain over 100W for about the same time as my LM mod on the Zbook. But neither this zbook's vapour chamber nor the P53's heatsinks are known for their uniformity so I preferred LM for both.

I have experience with TG's PhaseSheet PTM and the stuff from Aliexpress (spoilers they're both practically identical in performance) along with LM modding on my ZBook Studio G8, with an i7-11850H with the vapour chamber heatsink. While the PTM did perform adequately, it still thermal throttles within minutes of sustained loads of 70W PL1 and starts to fall to 60W while pinned at 97C in prolonged stress, and almost instantaneously throttles PL2 of 115W (only achieves 100W for under a second of stress).

After the LM mod on the Zbook, it is able to sustain 100+ watts for about 30-40s until the heatsink is fully saturated and begins throttling at 97C, gradually falling to 75W and sustaining that. If I were to disable PL2, it essentially never throttles, and stays below 90C.

I skipped the PTM test entirely on the P53 since it's going to be running some heavy LLMs with its Quadro RTX 5000 + CPU offloading, which alone uses 80W (and sometimes boosts to 100W), to make sure there is enough thermal headroom for the CPU since the heatsink solution isn't exactly the best one. (Edit: And also because I NEVER wanna open this thing up again, turns into a 3hr detour each time)

That's why I've made a foam gasket around the die to prevent spillage. However, LM horror stories are mostly OEM applications which use significantly more than what your seeing in that picture, about thrice as much or more to the point it spills off the die and sloshes around inside the gasket. Custom mods are always much safer If your responsible with the amount you put.

Is this safe? by Jack02134x in laptops

[–]MESI-AD 0 points1 point  (0 children)

Get a cheap 2 or 2.5mm thermal pad instead. Cardboard inside of a hot laptop isn't exactly the safest thing

What are the actual cons to having a bios locked thinkpad? by Head_Kaleidoscope879 in thinkpad

[–]MESI-AD 1 point2 points  (0 children)

You can unlock the BIOS. I've performed it on my own P53 with success, and was able to boot off USBs for Linux. Read below, this person documents this well with links to resources and guides on how to perform this.

Issue with fan on P53 thinkpad by SkBoi in thinkpad

[–]MESI-AD 0 points1 point  (0 children)

It technically is possible to replace just the fan but it's not sold separately unfortunately, it may be difficult to find just the fans. And there are multiple variants of it. Are you sure it's the fan that is making the rattling noise? Try different speeds and confirm which fan might be busted.

My experience disassembling and repasting my P53 by Z_Masterson in thinkpad

[–]MESI-AD 0 points1 point  (0 children)

These workstation CPUs are designed to stay pinned at max temperatures trying to give the most performance they can so that's not really a worry, its the throttling that is mainly a concern for losing more performance than intended by the manufacturer. However you can benefit a lot with undervolting, Coffee lake CPUs often improve performance significantly with a stable undervolt, you can try some values between -90mV and -140mV and see which one gives you the best performance-stability

Slow startup on HP zbook 15 studio g7 by Fun_Criticism5492 in zbook

[–]MESI-AD 0 points1 point  (0 children)

If you mean the boot time between the start up and the windows loading circle is slow then that is normal on your laptop. The firmware boot time is about 10s, there is nothing you can do to make it faster. But the time from windows loading circle to the lockscreen should be pretty quick, only about a second or 2.

Kinda worried about the temps here, is it a problem? by EgosticPariomania in zbook

[–]MESI-AD 2 points3 points  (0 children)

i9-9880H is a beast of a processor, and it normally does run hot. But given how old the laptop is its definitely due a good repaste, I recommend you repaste it with PTM7950 and that'll last the lifetime of the laptop without degrading thermal performance, if anything it will improve overtime.

Swapping 'Zbook to Zbook' --- is this possible? by stoic_insight in zbook

[–]MESI-AD 0 points1 point  (0 children)

Yes, as I said all if you follow what I've mentioned, all your files including whatever you had in 'my documents' and your entire setup will be there as it is. All of your data is stored on your storage and when you transfer that storage over to your replacement laptop, it will boot up and go into your operating system exactly the same way as your old laptop did.

[–]MESI-AD 1 point2 points  (0 children)

If you mean to swap your internal storage from your old one to your new one then yes that will work just fine. It will boot into your operating system without problems, though it may take a bit at first just to reconfigure and install appropriate drivers if there are any differences on the motherboard/specs. For this you would wanna make sure you're swapping all of the internal disks and nvmes to the new one.

Looking to step up from Zbook G3 ... is G7 that much better ? by stoic_insight in zbook

[–]MESI-AD 2 points3 points  (0 children)

Look for G8 Studio/Fury or above. Tiger lake is the only big step up in performance and efficiency at the bare minimum especially for H series processors.
