2019 17" Acer Nitro 5 AN517-51-56YW (GTX1650) [9th,4C,H] + RTX 3060 Ti @ 32Gbps-M.2 (ADT-Link R43SR) + Win10
So I have an Acer Nitro 5 AN517, I bought back in 2019 for around 550$ mainly because back then two M.2 PCIe 3.0 X4 was very rare, meaning I could have both my M.2 SSD and an eGPU working at the same time.
System specs (model inc screen size, CPU, iGPU, dGPU, operating system which eGPU is being used)
RAM: 16GB dual channel 2666MT/s
Display: Laptop internal display
dGPU: GTX 1650(50W) (disabled)
eGPU hardware (eGPU enclosure, video card, any third-party TB3 cable , any custom mods)
Zotac RTX 3060 Ti Twin Edge (damaged)
ADT-Link R43SR M.2 eGPU adapter
CoolerMaster MWE 450 White PSU
The GPU is a Zotac RTX 3060 Ti Twin Edge and it is a beast. From intel GMA 4500M to 840M, GTX 1650, RX 570 and now RTX 3060 Ti. Unfortunately I damaged the card, I don't know exactly how but one of those very small capacitors/resistors around the GPU Die broke off without me noticing. I was trying to apply Conductonaut to it and I just noticed it missing the card is running fine without it but the overclock headroom took a hit, mostly memory overclock. It only needs an 8-pin connector to function.
Here is the dual M.2 PCIe I was talking about earlier. It's very common nowadays. I'm using an ADT-Link R43SR works as intended and I'll ALWAYS recommend it over the EXP GDC extensions. the connector itself needs a 4-pin floppy connector to get power.
The CPU and dGPU themselves have liquid metal as their heat conductor. The CPU used to throttle horrifically without it. With it installed it's way cooler and there is no throttling anymore.
For power I'm using a CoolerMaster MWE 450 White.
this is how I jumped the PSU.
These are the performance figures.
Comments (eg: how has the eGPU improved your workflow or gaming)
Thank you eGPU community, I could've never done it without you.
P.S: Now I have this pain in my butt because the laptop fans are constantly running on high speed even though the CPU and GPU are below 40C. I have a guess as to what's going on but I have been unable to fix it so far. I believe it's the PCH temperature that actually triggers the fan not the CPU nor GPU. I've been all over the web asking out for help to try to unlock my BIOS advanced settings to be able to take control of the fans. After a whole week I got help from this person on this site.
He helped me unlock my bios and now while I have my advanced BIOS setting unlocked I really can't change anything. Whenever I change a setting it shows as it has been applied but when I boot into windows I get trolled. I go back to the BIOS, the settings show as they have been saved but yet they have no effect on the device. I tried the CPU power configurations, the PCIe configurations, the Thermal configurations and none of them actually apply anything.
This issue is extremely annoying if anyone has anything that could be of use please don't hesitate.
@rog195, if you unplug your eGPU system the problem disappear? Is it just with eGPU plugged in?
Check your power plan and your fan profile on Acer Nitrosense app.
Does the fan ramp up when putting the eGPU in use, consistent with PCH load also ramping up? If not sure, consider using HWINF64 to see if you PCH temperatures come up in the sensors view as it does for Dell systems to monitor it's temperature.
If fans do seem to ramp up with PCH increased load, then one fix would be to build a bridge using thermal pad material from your PCH chip over to your heatpipe to wick off heat.
@nando4, the PCH temperature is above 60C just by having the eGPU connected and above 70C when it's under load. Your way is a bit costy but I'll do it but first I need to know how effective it will be.
I'm looking at thermal pads on the local market and all they have are very small sized 50*50*1mm pads and I'm not sure having to buy three of those will be very efficient but idk I haven't worked will thermal pads before.
My initial plan was very sophisticated and hard. Get the BIOS to change fan activation point to a maximum so the fans never start then use the nitrosense app to get full control of the fans via custom fans. If you tell me your way will work just fine, I'll go for it.
@rog195, an intermediate step before doing that would be to boot with the NVME SSD attached to the slot, sleep (not suspend) the system, attach the eGPU, resume and perform tests. Idea is to get the ACPI fan thresholds to be set as if the SSD is attached .
@nando4, what do you mean exactly by “sleep not suspend”?
Because I did it with normal sleep button and got a black screen probably because I took out the ssd and put it back in.
Edit: I even got error 43 after boot, had to reinstall the driver and rerun the error 43 fixer
Does a constant read test from the SSD, something that would also stress the PCH, cause the laptop fans to go?
You may want to re-enable the dGPU just in case you had inadvertently disabled it's ASPMs, loading up it's temps.
Since no one on gods green knows how to fix my fan mess, I'm going with the only suggestion I got, I ordered a couple of 50*50*2mm thermal pads and I'm going to use them to transfer the heat form the PCH to the heatsink, hopefully it’ll work as expected.
