Seeking Help: ASUS TUF Dash F15 i5 12450H CPU Performance Issue After RMA

afterafterNORMAL SCORES (BEFORE)NORMAL SCORES (BEFORE)

CPU not performing upto mark. Clock speed not reaching 3.5ghz on e core and 4.5ghz on p core. and no longer is cpu pulling more than 40 watts under load. Due to this cpu performance is decreased drastically. I am on the latest of every update possible of windows and drivers. Please help me in this.

#ASUS_TUF_DASH_F15(2023 i5 12450h 16gb)

I did rma for fan change for my asus tuf dash f15 2022 i5 12450h. After change of fans and repaste my laptop cpu performance dropped drastically which was evident from cinbench multi core scores which were around 7k. So for the same service center replaced the motherboard and my scores were back to normal but backlight was not working so I gave it to them. After recieving back I saw my cinebench scores were again too low and cpu was not pulling above 40watts, normally it pushes max upto 65 w and hover around 45-50 w. But as said by service center that they didnt opened the laptop they just did software updates. By insisting they again changed the motherboard but after that too my scores were not back to normal on cinebench and my cpu never hitted 3.5 ghz on e cores and 4.5 ghz on p cores and also didn't pulled above 40watts under benchmark. I am attaching ss of cinebench scores when it was normal performing before  any of rma. 
please someone help me out in this regarding what could be the possible issue which is going on. As as of now the motherboard is changed twice and its new. The cpu never pushing to 3.5 ghz as of before neither 4.5 ghz on p cores. I am too woried regarding this.

Check Armoury Crate and make sure the fans are both spinning at max speed.  Also make sure you are on the Turbo, not Manual profile.  Also, paste a screenshot of HWInfo64 when Cinebench is running, not after it's done.

Fans spin max after 3-4 minutes of cinebench running. Instantly fan do not reach 6000 rpm. They do 4500 rpm first and after 3-4 min they go to 6k rpm. In AC it's in turbo mode already. The thing is cpu is not pulling more than 40 watts now and before it was pulling upto 65 watts. Hence the performance is not upto mark.

Can you paste a screenshot of HWInfo64 when Cinebench is running?  It looks pretty clear that ASUS incorrectly repasted your laptop (as it's thermal throttling), but I just want to make sure.

Also, make sure you're in Eco mode when running Cinebench (or in the same mode you were running Cinebench in before doing an RMA).  If your laptop is in Default or Ultimate mode, the discrete GPU will be pulling a good bit of power even when idle, which makes the CPU overheat easier (as there are heatpipes shared between the CPU and GPU).

WATCH THE CLOCK SPEEDS OF CORES TOO THEY ARE TOO NOT HITTING FULL EVEN P CORES ARE ONLY GOING 2.8ghz -3ghz UNDER CINEBENCH. AND MOREOVER THEY USED TO GO 4.5 GHZ ON LIGHT LOAD WHICH THEY DONT GO NOW ANYMORE.Screenshot (5).png

Yep, this is clearly Asus's fault.  As you can see, Armoury Crate and HWInfo64 show that the CPU package is at 95 C, which is the thermal throttling temperature Asus sets.  Considering it's drawing only 44 watts while thermal throttling, they must've incorrectly repasted your laptop, or the motherboard was shoved in incorrectly and can't get proper ventilation.

You can either try asking Asus to replace/repaste your motherboard again or try to do it yourself.  Also look at a disassembly video of your laptop model to make sure the inside of your laptop looks exactly the same as in the videos (the motherboard or heatpipe assembly could be positioned incorrectly).

One other thing, try running Cinebench with your laptop held up in the air (so the bottom isn't touching anything) and see if the results return back to normal.  The surface you have your laptop on (ideally a cold, flat surface) greatly affects how much ventilation your laptop gets and therefore your temperatures.

My concern is that the cpu clocks never pushes 4.5 ghz anymore no matter how low the temps are. And previously too the temps went 95+ under cinebench but it performed much better and pulled greater power

Try running Cinebench single-thread and seeing if it hits 4.5 ghz.  Unless you're running an intense single-core workload, your CPU should not be hitting 4.5 ghz (to save power).  Also make sure not to look at task manager, as it displays the incorrect clock speed for hybrid CPUs (use HWInfo64).

ok sure. But what is the solution to this should i repaste it myself I have pretty well experience in that as I own computer repair shop. I am thinking of ordering gelid gc extreme for the same.

I would trust you more than an Asus employee to repaste your laptop so I would do it yourself.  That being said, if you're only concern is it not hitting 4.5 ghz, this is caused by something else unless you're thermal throttling at 95 C.

I've never repasted a device, so you'll have to figure out which thermal paste you think is the best (I've heard Thermal Grizzly Kryonaut is).
