Pushing the laptop performance envelope
-
I just got a Lenovo Legion 7i with an i9-13900HX and an RTX 4090m It is a beast. However, it craps out even on older games like Fallout 4 due to thermal limiting. This thing gets hot. Putting it on a laptop cooler tray is basically necessary for gaming. My plan is to rip it apart, and upgrade all the thermal solutions inside with the best money can buy, and maybe add more on the GPU and NVMes Ain't technology grand? We're down to 5nm lithography and PC thermal situation has only gotten worse despite that. Now I'm not sure if I want to gut this expensive new machine myself or make Geeksquad do it.

I looked up the specs on the CPU & GPU: Intel Core i9 13900HX - Max Turbo Power: 157W RTX 4090 Laptop GPU - Board Power: (up to) 150W That's a lot of heat to dissipate! :omg:

Indeed. These modern laptops however, have great cooling setups. I think the thermal pads on this could be improved though, as is often the case. I've been thinking due to their better power per watt performance, and generally lower power consumption, an AMD may have been a better choice for a laptop CPU, but I'm still happy with this, and my primary heat issues are from the GPU, not the CPU, which seems to bench fantastically in performance mode. The GPU is running hot, I can tell, because it's benching lower than other 4090 mobile GPUs - lower than average for that model.

As far as I'm aware of, the whole RTX 4xxx line has (had?) thermal issues--or at least it did upon initial release...even in desktops with plenty of room for air to flow. I can't say I'm terribly surprised hearing about this with such a beast sitting in a laptop.

Better idea is to send it back to Lenovo and get your money back. Then go buy a Dell or Surface Laptop.
Nah. Dell's don't rate very well in this tier, and surface laptops are glorified tablets. I don't want something that will make me miss my desktop while I'm out.

The 4090m uses far less watts than the desktop 4090 despite having the same basic architecture. It benches right between a 3090 and 3090 TI desktop at about half the wattage. And yeah, these cards can have thermal issues. My 4080 desktop has been cool as a cucumber - most I've ever hit it was at 67C when I forgot to turn my chassis fans up. Much cooler than my 2080TI. The issue I've heard with the 4080/4090s is their RAM runs hot, and could use some thermal pads, plus some bad pads/adhesion from the factory on the core components. I'm hoping to just shore up the GPU in this chassis with some additional thermal management.

Had both. Two Dells and three Surfaces (one personal and two company issued). Dells are solid, well build machines. MS Surface is a complete poop. Unusable, goofy, fragile and expensive marketing driven nonsense.

If a professional does it they are liable for mishaps. If you do it you're responsible.

Might be anyone doing repair would void warranty, but at least if a pro does it they will back it.

That's true, but I was thinking if anything else goes south you might be stuck with a hefty repair bill.

No if they are professionals, you go in negotiate a price and that's it. It's a brand new unit nothing else should go wrong, unless they cause it.

I would recommend taking a look at the Windows advanced power settings for Processor power management. I throttled mine to avoid the fans blazing when playing games :-\

Windows power settings can't deal with the extra power options for my GPU(s). I have onboard and discrete both. My lappy switches between them to save power. Unfortunately, this means some programs wind up using the wrong one. Like I had a benchmark program that insisted on doing its 3d benchmarking on my onboard graphics. You can change from automatic to discrete in BIOS or through a utility that ships with the laptop. My CPU is actually relatively cool, and under normal workloads my laptop isn't that noisy. Gaming of course, is one area where the fans really kick on. And that's where the discrete GPU is necessary. Unfortunately, my discrete GPU seems to be thermally throttling itself more than it should have to, meaning the cooling situation probably isn't altogether ideal.

'Should' being the operative word, sometimes things happen.

Applying expensive thermal paste may not be the best way to go. Chances are that the thermal paste currently applied is good enough and changing it may make minor differences but nothing significant. Most heat dissipation issues are usually caused by the lack of airflow. Maybe the fans aren't running at full throttle, or the fan blades are not big enough which common in laptops. Or maybe the laptop's design hinders the airflow. If it were up to me, I'd rely on experts to do the job. Sadly there aren't many. Could also consider returning if the issues can't be fixed permanently.

what did you expect with such power usage in a small space ? surely Lenovo, or reviews on the web, warned about this ?

I expect my machine to behave like a new Lenovo Legion 7i 16" 4090. It does not. It lacks the thermal characteristics of one of those machines, despite my machine supposedly also being one. Ergo, it's probably getting returned for repair.

Also, no their reviews don't warn that you might get a lemon.

Not paste. Pads and copper sheets. If they didn't work, then they wouldn't put them on NVMes to keep them from melting. If it didn't work they wouldn't put them on the laptop internals in the first place. It it didn't work, I'd have no shoddy workmanship in the laptop to go redo in the first place.
