Thoughts on how to fix an insanely hot laptop (75C idle, 100+C load)

Recommended Posts

There isn't much of a haze, it is visible scratching and other pits. Even after cleaning it off with paper towel + smidge of thermal paste as some rubbing compound and then a micro fiber cloth. It has a dark neigh-black rectangle where the die makes contact. When I first pulled the heatsink off, the thermal paste didn't even cover the whole die.....

I'll try to find another heatsink before attempting to swap the radiator.

I'll shoot ya a PM.

Paste not covering the whole die will increase temps dramatically.

also remember to get a good and recommended brand thermal paste my alienware m18x-r2 dropped 5 degrees celsius with thermaltake.on my 3610QM stock, i`m preparing to overclock just figuring out how to mod my bios so i can overclock it from there instead of windows.

And it was like that from the manufacturer..... I wasn't pleased.

Alrighty, this thread is kinda res'd, but I figure this is better than making a new thread.

Pulling the sensor pin out makes the fan run full tilt. Which is great for temp! Here is a picture catalogue of what I did, brought to you in potato quality pictures (the image meta-data says so!).

My not-stock-at-all fan. Certainly looks terrible. But I love the airflow from these centrifugal fans.

I was thinking of keeping the sensor as not part of the fan extender cable, but decided against for reversibility in the future - I didn't want to damage the fan wires.

Cutout hole for the switch, the lockclip thing for the docking station keeps the switch from being toggled on accident.

Rough test to see if the wires are long enough/etc.

post-6146-14494995824343_thumb.jpg

The completed adapter/switch thing.

post-6146-14494995824741_thumb.jpg

Rough layout of how it goes.

post-6146-14494995825211_thumb.jpg

The switch is currently set to the sensor connected setting.

All nice and pretty looking.... for what it is.

post-6146-14494995826083_thumb.jpg

Fan error,,, more like fan fixed!

post-6146-14494995826493_thumb.jpg

Ran TS Bench. The CPU wouldn't break the 80C mark!

For those curious, the fan extender cable was from a pentium 3 dell latitude. I don't remember the exact model. It was later filed under 'T' for 'Trash.' ;P

There are alot of factors to know as to why laptops get so hot some being

-Dust THIS BUGGER clogs your vents and prevents air flow from moving in or out so I recommend you clean that out asap

-Thermal Paste as you've said you've already repasted it so no worries there

-Room temperature one of the main parts to cooling a laptop.... If your room is above 25*c expect a hot laptop...

-Cooling fans this may sound simple as hell but when using cooling fans I really recommend you open tue maintenance hatch to the laptop, instead of blowing on the case, you actually cool the coper heat-sinks, with older laptops they tend to heat up much much much much faster and idles at very high temps...my 6 year old laptop will blow itself up without a cooling pad, and whats even more funny is that even with a cooling pad it over heats, this forced me to leave the maintenance hatch open and vola.. Fixed the problem

-Quality of the fan, have you checked that it is spinning at its greatest rpm? And that its still healthy? A slow spinning fan wont help.

Woah, this is late reply but I'll answer anyways.

Dust: I blow out my laptop monthly, it stays very clean.

Thermal Paste and die pressure have had the largest impact essentially solved the issue.

Always in a temperature controlled environment. I'm bad with a useful unit of measurement (Celsius) but room is ~70F.

Cooling fans: minor improvement. thermal paste + die pressure had the most dramatic effect (over 20C temp drop).

Fan: Highest CFM fan I could get my hands on (I see 100+ laptops a month so I can pick out which have nice fans). At full speed (with switch mod) it MOVES! Funny in class.... it is immensely loud >_>

I would say check for an air gap if so seal it with duct tape (caution may void warranty . I would also check to make sure that the heatsink(s) is/ are making contact. I would also try (carfuly) testing the fan externaly by giving it the required usually 5v for laptops) voltage and amperage, carefully avoiding shorts. if it doesn't work properly I would try to find a replacement.

without going overboard with the modding,

- Clean the the laptop with a blower to insure smooth airflow

- reapply thermal paste with a high quality one.

- use a decent laptop cooler

- use a custom fan controller and speed up the fans in high load

      Over the last 10 years I've found laptops throttle the processor speed in order to keep fan noise down. I prefer the fan to run noisily, and the processor to run at full speed. I've developed tried and true mods for lappies and have demonstrated their effectiveness.
       
      I have two Lenovo W541 laptop workstations with I7-4940MX processors and discrete nVidia graphics. On one I overhauled the cooling. Copper shim between CPU and hsf, AS5 on both sides. Shims between hsf and inductors near CPU and gpu, and shim on the gpu.
       
      Used 'thinkpad_acpi' Linux kernel module to set fan to max speed. Ran mprime (prime95 for Linux) AND Unigine Heaven, alternating,  to cure the AS5. Then ran mprime. Temps were slightly high. But laptop processors tend to run hot. 
       
      The I7-4940MX is a 3.1 GHz, 4.0GHz. Turbo processor. The modded machine ran at 3GHz. continuously running mprime, for weeks. The unmodded machine with the same max-fan-speed software tweak and stock thermal-interface material, throttled to 1.7GHz.  at the same running temps.
       
      Clearly, laptop manufacturers are robbing performance off the top, by inferior cooling hardware and materials. Granted, getting the cooling mod to all fit together correctly with smooth, flat surfaces requires hours of work and materials not normally found sitting around the house.
       
      I normally do not mod the CPU die. I abrade copper surfaces down to 1500 grit paper, and then polish with scapings from a bar of buffing compound. Everything is done on 1/2" plate glass to maintain flatness. The final mirror polish is done with the compound granules on a clean, damp cloth.
       
      Desktop processors mostly have slightly raised corners, so smoothness is not as much of concern. You're going to get thermal-interface compond completely covering the center of the processor. The ideal is to fill the microscopic gaps between the cpu die and the hsf, but where there is metal on metal, have it be. 
       
      Metal to metal provides 100s to 1,000s times the heat transfer of thermal paste. But, on a desktop, there are more effective cooling solutions than moving air. Most user are satisfied with their laptops, because the processor doesn't run full speed long enough to make a difference.
       
      But I enjoy tweaking, and I do processor-intensive work, like batch editing 100s of large images, video rendering, security testing, password recovery, network testing; that are all severely compromised by poor, stock laptop cooling solutions.

      Hi all,
       
      I'm debating whether or not to replace the thermal paste in my Lenovo y510p. I've started overclocking a bit, and I have an external fan, but I would like to not have to run the fan as fast because it is a little loud. I have been reading a bit about different thermal pastes, and I'm wondering if there is even a big difference between stock thermal paste, and something like the liquid metal from thermal grizzly. It sounds like it'd work better, but I don't want to fall for a good marketing scheme. If anyone has experience with this and has or hasn't seen big differences, your input would be greatly appreciated.
       
      Thanks in advance!

      Hey guys, first post, but I thought I’d discuss my heatsink fan retrofit in my old M14x r1. 
       
      Old fan was loud and not very efficient: the air transfer rate was around 2 cfm (I’m assuming cubic feet per minute). Finally had enough and decided to swap out the crappy r1 fan/coughing pinwheel for a r2 fan (rated at 10.4cfm). 
       
      I found an old r2 heat sink on eBay (beware though that the heat sink for the r2 will NOT fit the gpu/cpu configuration for the r1. HOWEVER, the fan of the r2 heat sink it is attached to is a carbon copy fit into the r1 MoBo. A few philips head screws and a seal of good electric tape and BAM, you’ve got a significantly cooler and MUCH quieter intake fan in your old R1. 
       
      My CPU temps from before were around 87-88 max load in FSX, 65 for the GPU; bear in mind this is after a repaste. Now with the new fan, I’m not going over 77 degrees on the CPU, and the gpu stays around 58, all while being MUCH quiter. I’ll post pics of the walkthrough if anyone is interested.
       
       Just thought I’d share with all you fellow loonies trying to squeeze every last frame and degree out of our “portable toaster ovens with a screen and keyboard”.

      First I want to thank the community, who have inspired me to do this project.
      I will give you guys the chance to follow me on this journey.
       
      I hope you will all help me come up with ideas, techniques and parts that could become handy.
       
      This modding may be possible to convert to allot of laptops.
       
      Let's begin!
      Here is the measurement of the went hole.
      77mm X 16mm

       
      I have 2 ideas for what can be done.
