Cooling a 5750G?

Recommended Posts

I've jus bought a 5750g second hand (i5 2430M 2.4 GHz & nvidia 540M 2GB) and it's running really hot, i'm getting 95+ temperatures on both the cpu and gpu while gaming, so big thermal throttling framerate drops apply. The thing is that the fan looks almost perfectly clean so i'm discarding that option but given the fact that this laptop only have one heatsink for the cpu the gpu and the chipset and that the fan is not providing enough air flow i want to ask you for some cooling tricks to lower the full load temp to 80 or 85.

About the fan, it doesn't achieve the same rate under load that the one it gets while booting, just after powering the laptop the fan goes crazy and then drops to it's usual rate and that's not enough.

At the moment i'm thinking on:

-replacing the stock thermal compound

-buying a cooling pad <-not a big fan of this one, i think the system should take care of itself

-hacking the fan to bypass the pwm control and soldering it directly to a 5v line, jet engine rpm on demand.

After you do the repaste I think you will be under 85C.

Also usually you can't see if there is dust between the heatsink and the fan without taking it apart (literally pull the fan from the heatsink).

I hope i can get to 85 only with the new paste wi'll see. In this laptop you can actually see the fan in trough a vent in the bottom, lighting it with a flashligth it's possible to see if the blades are dusty, anyway i'm going to open the laptop for repasting so i'll clean the fan while i'm at it.

I had same problem. You should open fan itself and clean dust inside, use Arctic cooling paste and NEVER play a game without cooling pad!

Also, Acer made small simple app that in theory should allow you to run your cooler at max speed. App name is Fan Controller (how originally), you can download it from Acer site. In my case, fan does go max speed, drops temp 40-50 C, and then stops completely until temp rises. Unfortunately, sometimes it doesnt work at all and I have to restart system in order to speed up fan.

I still don't like it. If I turn the laptop on and forget to start Fan Controller, temp goes to 70 C. I am going to hardwire fan to 5V supply so it runs at max speed all the time. I just have to figure out where to hijack 5V from. If anyone knows, please do tell.

Do the repaste, I had the same issue with my Acer 5750G with GT 630M and an i3 (Given the i3 probably produce less heat) Anyhow I was hitting 85-90C constantly. I repasted with Artic Silver 5 (Still good stuff & easy to find) I always do a good tiny X of thermal paste in the middle I always found it to work best than the dot)

Now I idle around 40C and pushing it I don't go past 65-70C its been great, Do it for GPU&CPU. Clean the fan out and clean the cooling fins of the laptop cooler. I think there is a few tiny thermal pads in there if you do find any don't throw them away reuse them or replace them-

I would also recommend repasting it. Especially because you bought it second hand and the notebook is from 2011.

I had the same notebook some years ago. It ran very hot. Replacing thermal paste helped a lot. In combination with the "Fan Controller" Application, it was o.k..

But had to replace the paste pretty often.

      Hello all! Im posting this here in hope to receive some orientation or help regargind my egpu project.
      I have my old and trusted Acer 5750G and I’m still using it everyday for work. I’m a photographer and it has worked quite well with some upgrades:
      -Upgraded i5 to i7 2630qm.
      -Upgraded ram, 8gb to 16 gb.
      -Upgraded HD to SSD.
      Some facts:
      – I have the unlocked bios so I was able to set the mpci port as “hot pluggable” and I can also deactivate the dedicated nvidia 630m from the bios itself.
      – I have bough this case [PCIe PCI-E EXP GDC External Laptop Video Card Dock / Laptop Docking Station (Mini PCI-E interface Version) ] that will arrive home in 10-15 days.
      – I have ordered a wifi usb card.
      I was thinking in getting a nvidia 1060 6gb and plug it to my old laptop using the mpci port. I ask for your advice and knoledge regarding this:
      1- Is this a good card choice?
      2- Will I face any problem with my setup or there is something important I should take into consideration?
      3- Will software that uses CUDA (photoshop and premiere, for example) get reinforced with the new card?
      4- How much processing power will get lost for the “small” port I will be using?
      Thanks a lot again, and sorry for my english mistakes!!

      Dear all,
      I hope someone can help me out here.
      I have an Acer Aspire E4-471g Laptop. Intel Core i5-4210U NVIDIA GeForce 820M 16gb DDR3 RAM 512GB SSD
      I have an EXP GDC V8 Beast eGPU adapter. I use a power adapter to juice my eGPU by Dell Netzteil ADP-220AB B 12V 18A 220W P/N Y2515 REV A02
      I have a Zotac GeForce GTX1050ti 4GB
      The Problem:- I did the normal procedure, disable the eGPU. Took out the wifi and replace it with the mpcie cable.
      Switch on the computer and I have a blank screen. No screen at all on the laptop screen nor in the external monitor.
      Is there a best solution? I have seen the Setup 1.3 but I will do that if that is really the necessity.

      Hi everyone,
      I hope I'm not going to write off-topic;
      I own an Acer Predator 15 (G951) notebook, and it never gave me problems before; I've never used the integrated audio jack port because I usually listen to music and other stuff through Bluetooth headphones, but few weeks ago I noticed that putting a jack connector in the jack port only deactivates the sound from the pc speakers, but the headphones don't appear in the "devices" section, and the sound coming out from the headphones is really faint and distorted (only if the system slider of sound is at the maximum level and the sound should be very noisy, when the level is lower I don't hear anything at all). Also, when I put a jack in the microphone jack port of the pc I hear the classic sounds of the jack which touches the pin connectors inside the port, but it doesn't happen with the headphones port. I tried almost everything: I changed a lot of headphones, both phone headphones with a single jack and pc headsets with two jacks (for the headphones and for the microphone) but every time it's the same. I installed and reinstalled a lot of different versions of the audio drivers, both from Acer and the productor (Realtek), and nothing changes, I also tried with Ubuntu and it's the same. What could be the cause, and can the problem be solved without any technic intervention? Anyway the warranty for my pc is still valid, but the assistance should be the very last resource (I should do a backup of everything and format and so on). And, the last question, I flashed a custom VBIOS some time ago, does this compromise the warranty? Should I really reflash the original VBIOS or it's not so likely they're going to check on this?
      Thank you all for your attention!

      Hey, there. Few month ago I bought this laptop and it’s awesome, though it has some cons. I’ll describe everything in this thread. Also I’m searching for someone, who will share his time and help me crack its’ bios

      Acer Predator G9-593

      Intel Core i7-6700HQ (2.6Ghz/3.5Ghz) (https://goo.gl/dehk14)

      Nvidia GeForce GTX 1070 (8Gb GDDR5) (https://goo.gl/z2aEFL)

      15.6inch 1920x1080 (G-Sync) (IPS) (Matte)

      16Gb DDR4-2400 / PC4-19200 (2x ACR24D4S7S8MB-8)

      1tb HDD + 128gb SSD

      Windows 10 x64

      Nvidia driver - 378.49

      4 USB 3.0, 1 USB-C с Thunderbolt 3, HDMI 2.0, Display Port, SD Card reader, Gigabit Ethernet, Audio/mic

      Several reviews:


      Also this laptop has a bigger brother – Acer Predator G9 793, absolutely same laptop but with 17inch panel, 4k variant and 4 speakers.

      First of all, good sides:

      Solid construction, soft touch martial all over the case, no glossy parts.
      Sound is really loud, even basses exists here, though I can’t say its best of the best.
      Outstanding performance, take a look at this data https://goo.gl/oyF9dl, almost all games run over 60 fps in 1080 and over 30 fps in 4k. Take a look a several gameplay videos that I’ve captures on this beast, all of them were captured in 4k resolution, on ultra settings with no AA:

      Rise of Tomb Raider - https://youtu.be/rNRMnytsC2c
      The Witcher 3 - https://youtu.be/dJicr6we0z0
      Quantum Break - https://youtu.be/PNofDssIgS4
      (1080 with max AA) Crysis 3 - https://youtu.be/H1ja_BhD0-Q
      Resident Evil 7 - https://www.youtube.com/watch?v=LiF-zhTwNDE
      Battlefield 1 - https://www.youtube.com/watch?v=ypOEnJ9KbKs
      Dishonored 2 - https://www.youtube.com/watch?v=Jhtvj4BkiMc

      Only in  Ghost Recon Wildlands I had less then 30 fps https://youtu.be/lbeW9PZvsUo

      And bad sides:

      Thought laptop is 15inch, its bulky as hell, thank god it looks okay, not like some previous gaming crap lappys: http://www.notebookcheck.net/uploads/tx_nbc2/toshiba_qosmio_x305_q725_01.jpg
      Screen has some ghosting, previous static images can stay on screen for some time. Not this laptop, but image illustrates the issue: https://goo.gl/H42OCJ 
      Some laptops has overheating issue on CPU. Though in rarely influence on performance, its still sad thing to have in such big laptop. Issue described in this thread: https://goo.gl/KjNNBN, simple CPU repasting solves the issue: https://www.youtube.com/watch?v=DVEpuZNWLxw
      Stepback in turms of battery life since g-sync laptops doesn’t support nvidia optimus. Around 4-5 hours of work.

      Hollo, It's my first post. Few weeks ago I made setup:
      Acer Aspire V3-772G
      i7 4702MQ, 4 cores 2.2 ghz.
      8GB DDR3 ram
      1 TB 5.2k HDD
      120GB SSD
      Windows 8.1 works on SSD
      BIOS InsydeH2O 3.7 fully unlocked
      My external setup :
      EXP GDC beast v7
      GTX 1060 6GB MSI ARMOR
      600W PSU
      please note my PSU and GPU is completely new.
      I can play games very well, however games randomly  crash it takes from 5 to 40 mins to crash. Also I noticed crash sometimes happens not playing anything, desktop turns black. That's my only problem and I can't find a fix. Also please not after crash Windows recovers quickly.
      what I have tried :
      - Because Acer has no white list, I have unlocked BIOS and disabled dGPU, after that everything started to work. Please note my dGPU is broken, can't do any 3D render for some reason...
      - I have tried few different versions, like Windows 10, windows 7 and Windows 8.1. Now currently I'm using Windows 8.1 it seem to give best performance.
      - Nvidia drivers I have tried is only few versions, however game still crashing.
      -I haven't tried 1.30 setup that much main reason is that, I don't really know what to do there and also can't start Windows after configure.
      - Mainly I'm testing on GTA V, however I've tried different games like Tomb rider or wither 3.
      - Also played with EXP GDC v7 switches, these makes no effect at all.
      - switching to gen1 in bios also made no difference. I only receive poor performance in games.
      - I have also done cpu monitoring all seem very perfect. No problems with power and so.
      lastly, I'm waiting for any help what I could do with my setup. Also you can ask me for any information I'll be happy to provide it.
      please help me to fix this problem.
