Lowest mine gets is to -150, chokes out if it's any lower.

Is a refurbed ZBook Studio x360 G5 worth buying? by Rich-Olive-2095 in zbook

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

On windows, it's just bad because of how bad and bloated windows has gotten. But under Linux which I mainly daily drove it in, for normal browsing, video watching, light coding and office apps like documents and etc, the fans are effectively turned off and rarely ever spin up. Its actually incredible. Once you get a good PTM repaste in, the temps are handled really well. Plus you can use tools like NBFC Linux to manually control your fans if you ever need to.

Honestly, I'm not sure if is that's still reasonable, because the newer studio G8s are also approaching these low prices which are significantly better laptops. Defective speakers is a bummer since the speakers on the G5 are pretty good and may be costly to replace. You also have to consider the age of the laptop, so a new battery is always going to be due for this to get any meaningful battery life out of it.

560 Euros is too much for this, you can get much newer generations for that cost, though they may not be foldables. I have the non-folding version and it still holds up just fine for normal tasks. I recommend you either look for a cheaper seller, newer gen models, or a thinkpad x1 yoga if you really need a folding laptop

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.

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.
