What program do you use to monitor and work on fan temps for better cooling? Can I achieve better cooling by just fan control?

Hi there folks,

 

Long time lurker, decided to sign-up in order to be able to better tweak my 2570P.

 

After reading this whole thread, I've installed a 3632qm which runs nice and temps are 60-65 Celcius under load. It has 2X8GB DDR1600 Kingston so-dimms which run fine. Some questions:

 

1) This came with an HP 19.5V PSU adapter although some use it with a 18.5V HP adapter? Which one is better? Can I damage the laptop if using the 19.5V one? Both are official.

2) If the laptop is left alone and unused for long periods of time (2-3 months), the keys on the keyboard don't register properly. You have to hit them hard a few times in order for them to start working again properly. Is this a known issue with these laptops?

3) This is a used laptop. It has some profiles in the bios and I always login as "guest" into the bios. Is there any workaround around this in order to remove the old profiles? Bios version is F65, no idea if there are better unofficial modded bios versions out there.

 

Thanks

Both are fine. In fact, a laptop can handle even higher range of voltages just fine, and especially high-end ones like EliteBook series.

Yes, this is a known issue for laptops that were spilled on with Coca-Cola or beer :))

Stock+defaults should be always fine, unless you need something fancy. Maybe read what others achieved modding BIOS in that case

Got a ~$5 2xUSB3.0 card on AliExpress got very good speeds, but rather fragile build quality.

Hello,

 

I am wondering if someone already tried a vacuum cooler on the 2570p as seen below ? My goal is double :

1/ be able to use the laptop in silent mode (the default fan of the 2570p is not enough silent even at lower RPMs) so the vacuum cooler can "replace" the internal fan when the CPU is in low performance mode and

2/ reduce thermal throttling for the quad-cores in high performance mode (the default fan is not enough powerful, even with upgraded heatpipes).

 

Also, what do you think about thermoelectric pads ? A thermoelectric pad is like a "mini freezer" (doesn't need any fan or water to cool down something, but needs far more power). My second choice would be to use this pad plugged on an external powersouce (USB seems not enough powerful). Also, there are pads specifically made for smartphones, obviously they will not be able to cool down a full fledge laptop CPU but they could help to reduce the heat in power-saving mode, with no external battery. Nevertheless, didn't find suitable ones for the laptop, and here is a standard thermoelectric pad : https://www.amazon.fr/KIMILAR-Dissipateur-Refroidisseur-thermoélectrique-refroidissement/dp/B00ITMJPCU/ref=sr_1_2?__mk_fr_FR=ÅMÅŽÕÑ&dchild=1&keywords=powerful+laptop+cooler+peltier&qid=1616708231&sr=8-2

 

And a vacuum cooler :

 

Opolar LC05 Laptop Cooler with Vacuum Fan (Rapid Cooling, Auto-Temp Detection, 13 Wind Speed, Unique Clamp Design, Compatible with Cooling Pads)

I have an Opolar and I love it. It has both a temporary clamp-on or permanent mount option. I just use the temporary clamp when I want to use my 3940xm CPU, (this is not an endorsement of using the 3940xm CPU with the 2570p. I had the CPU available to experiment and probably am lucky that I don’t have any issues. I recommend reading other member’s recommendations), to encode video and it works great. No need to slow it down as it doesn’t thermal-throttle with the Opolar set on maximum speed. You can adjust the Opolar speed manually or set it to automatic. I have no other temperature cooling mods. I even just used the thermal grease that Intel packaged with the 3940xm CPU. I didn’t buy any special thermal compound. I’ve never been impressed with aftermarket thermal compounds. I like the Opolar vacuum cooler the best, because when I researched them, the other brands just sat next to the laptop. They didn’t include any clamping hardware. The Opolar isn’t silent, but I wouldn’t say that it’s sound is objectionable. It is a smooth sound even at it’s highest setting. Also, the clamping equipment came with 3 different-sized rubber seals. I used the largest seal and it works great. It fits between the USB/SATA port and extends to cover the rest of the right side of the 2570p clear to the back. The Opolar intake port then lines up well with the 2570p’s exhaust grill.
 

I still use my 2570p extensively for video work since it’s nicely portable and includes the optical drive, which I upgraded to one of the first Blu-Ray drives that is “4K-UHD compatible,” and still running it’s original BIOS so that it can read 4K-UHD disks while ignoring their copyright protection. Other mods are a Samsung 4TB SSD 860 Pro, 16GB RAM, Intel AC7260 802.11AC WAN adapter, (which is failing and needs replaced), and Windows 10 Pro set to delay Feature Updates for 18 months (maximum) and delay Security Updates for 30 days (maximum) in order to minimize problems.

 

I wish you good luck and maximum utility value from your modification choices!

So there is no thermal throttle with the 3940XM (and in consequence, all less power-hungry CPUs as the 3820QM, etc) ? What is the maximum CPU temps in ThrottleStop (screenshot) ? If there is no thermal throttling, this will be undoubtedly the best "simple" mod for the 2570p to unleash its full power.

 

I did some basic calculations and the 3820QM if there was no throttling would bring the CPU to more than 120°C (at full power the CPU is throttling at about 25W on my laptop, while its normal power is 40W on the 2570p), I find it hard to believe that this cooler can bring down the laptop to 20°C (at least) to limit throttling. I tried a lot of impractical cooling methods (even the freezer, lol) and never managed to bring down the CPU to less than 100°C with no throttling in full load for more than a handful of minutes. How is this possible ? Can you post more information (room temperature, CPU temps, run time, screenshots) ?

      Hello, A couple of days ago I got a new GPU but when I installed it into my computer I was unable to use it but now I know why. When checking the device manger I went into the events tab of my GPU when I went to view all events, I noticed an error it said " event 411 kernel PnP " and It also said Problem Status: 0xC01E0438. I believe this is why my GPU hasn't been working on my PC. If you know how to fix this problem or have info on how to fix this problem that would be greatly appreciated. I'm also using a EVGA NVIDIA GeForce GTX 1660.

      I'm having a problem where my PC is saying my eGPU is not usable, its detected in the Device Manager and it doesn't have the yellow triangle next to it. I cant use it games and the Nvidia Control Panel doesn't recognize it either. I'm using a EVGA NVIDIA Geforce GTX 1660. I'm using windows 10 and I tried DDU and reinstalling them and now I cant access the nvidia control panel. The GPU is not recognize on any other apps and I went on *********** and was unable to find my answer, Any help on how to fix this problem would be greatly appreciated.

      Title sums it up.
       
      TL;DR: we have a Clevo that runs a desktop CPU, one with those huge 82 Wh batteries. We remove the GPU and let it use the CPU's integrated graphics. How much time for the battery to go from 100 to 0? Is it comparable to an ultrabook's?
       
      I'm theorizing a mobile set with a static eGPU and an upgradable CPU. Given a hypothetical user that needs fast processing on the go and long battery life while retaining very high degrees of mobility, but at home wants a powerful machine to run most games, I guess that would be their best bet. It would surely be more convenient to keep everything in the same disk. And even though the thing would be quite heavy to carry around, changing CPU would be more cost-efficient than changing an entire laptop. (Not sure if I'm right here, and also I'm not sure whether the motherboard in a Clevo would be replaceable when the new CPU needs a different socket, which is another reason why I'm asking here.)
       
      If my above guesses aren't correct, then an ultrabook with Thunderbolt and without a dedicated GPU would be a better choice. If they are, then we would be carrying more weight in exchange of a more cost-efficient setup, which I think would be a fair tradeoff.
       
      Also I am aware of the heating problems that these laptops suffer from, at least compared to a desktop setup. Would they be solved by moving the GPU out of the chassis, and instead plugging it with an eGPU dock via Thunderbolt port?
       
      What do you think? Is it doable? If not, why?

      Hi,
      I want to show you my new project.
      I bought my laptop about 5 years ago.  It was never speed deamon, but for every day use, it was enough to me.
       
      Its specification:
      Intel i7-4700MQ
      Nvidia GeForce GT745M
      16GB RAM
      512 SSD Adata SU800

       
      Yesterday I bought Witcher 3. Of course on 1080p it's impossible to play, because of about 10fps
       
      So I make a decision to buy external grahpic card.
      I choose GTX970 and now I am looking for occasion to buy it.
       
      I've already bought EXP GDC v8.4d mPCI-E. It is used and cost about 30$.

       
      I will use ATX PSU to supply graphic card, because I have old desktop PSU at home.
       
      My plan:
      1) unlock bios
      2) buy GTX 970
      3) enjoy Witcher 3!
       
      BTW I try to cool down my laptop, so I replaced thermal paste to Kryonout Thermal Grizzly and make some tests. Temperatures and fps are on screenshots.
       
      1) laptop on table, playing GTA V 1080p

       
      - first minute (GPU core 1045MHz)

       
      -after some time, because of high temperature and GPU throlttling (GPU core drop down even to 400MHz)

       
      2) with thermalpad Glacier NC400 SilentiumPC

      - 30 minute and longer (GPU core drop to about 900MHz)
       
      3) without down case of laptop (like on picture with thermal paste) on thermalpad.
      Here laptop never drops down MHz and max temp are about 72 Celsius degrees.

       
       
      Bacause of that I bought second down case for my laptop and I will cut there additional holes.
       
      Greetings!
       
      I will describe next step when I get all stuff I need!

      Hello everyone
      I created a case for egpu using 2.5mm acrylic sheets. The first time I created a case to support a GPU + ATX psu
      Now I created another one for the GPU with an external Xbox 360 203w psu.
      the finish was not good but for my use it is already good.
       
      *both cases album
      *Construction of the second case 
      *adapting xbox psu to 8pin power (taken from 24pin)
       
      all made by hand with the tools I had.

      from Brazil.
