Hi Brad! I have an old laptop I like, but after a cpu upgrading, has an issue: thermal management. Yes, one problem was the insufficient mounting pressure. Yes, the fan has a low cfm output (5.3). No, it's not the thermal paste (currently using arctic mx-6). However, the dissipator thermal conductivity is intrinsically low, because the heat pipe is totally long 24 cm and has a U shape. So adding another heat pipe seems an option, and your suggestion seems valid. I have a question for you about turning the fan case into a heatsink: at first glance it seems an intuitive option. But after some investigations, I concluded that transferring heat on the fan case should create issues. Why? If that you have is a centrifugal fan, it gets air from the downside, and, with rotation, it accelerates it pulling outside. Now, the presence of a heat pipe on the fan case should create a hotspot right on the air inflow: so this means that the air, by rotating inside the fan case, gets hot, and then is expelled through the radiator. Shouldn't this actually diminish the efficacy of the entire cooling system? Moreover, i think that contact surface with the stock heat pipe is another important parameter that can be optimized: the more surface, the better? Could you show a picture with your thermal camera of your current setup? and, if you possess it, before the mod?
@BradsHacks3 ай бұрын
Commendable effort to reason about fan case issue, but you have reached an incorrect conclusion. (1) Heatsinking to the fan case, when you also have a fin stack heatsink at the fan outlet, is equivalent to adding a heatsink in series to another heatsink, because the air exiting the 1st heatsink (fan cover + heat pipe) enters the 2nd heatsink (fin stack). I think we agree on this. (2) As you pointed out, the air entering the 2nd heatsink is now warmer because it has already absorbed heat via the 1st heatsink. However, the heat that it absorbed came from the processor, so it already contributed to cooling the processor. Its additional contribution outweighs the efficiency loss of the 2nd heatsink. I will prove this mathematically using heat transfer principles, and later cite a real-world example. (3) The steady-state cooling capacity of a heatsink can be described by: q = ṁc(T_out - T_in), where ṁ is the mass flow rate of air [kg/s], c is the specific heat of air [J/kg°C], and T_out and T-in are the temperatures of air exiting and entering the heatsink, respectively [°C]. For convenience, let's label ambient air "1", air inside the fan "2", and the final exhaust air "3". Let's start with a laptop with just a fin-stack heatsink at the outlet of a centrifugal fan. The fan basically just pushes ambient air into the fin stack, so the system cooling capacity is: q_original = ṁc(T₃ - T₁) Now let's start heatsinking into the fan casing. The fan casing now acts as another heatsink, so: q_new = q_fan + q_stack = ṁc(T₂ - T₁) + ṁc(T₃ₐ - T₂) T₃ₐ distinguishes that the final exhaust air won't be the same temperature as before (T₃). ṁc is unchanged because we haven't changed the airflow. As you predicted, T₂ is warmer than T₁, because the air has been warmed up before it goes from the fan into the fin stack. By distributive property, the above equation simplifies to: q_new = ṁc(T₃ₐ - T₁) How does q_new compare to q_original? It depends on whether T₃ₐ >/</= T₃. With the additional heat being dumped into the flowing air by the fan casing, do you expect the air exiting the laptop to be warmer, cooler, or the same? (4) T₃ₐ will be warmer, because there is now more convection surface area - the air is flowing over more hot surfaces. Convective heat transfer over a heated surface is q = hA(Tₛ - Tₐ), where h is the average convection coefficient, A is the surface area, Tₛ is the surface temperature, and Tₐ is the ambient temperature. When you make the fan case a heatsink, you're increasing the overall convection surface area A, which means q (heat transferred) is higher: q_new > q_original Theory sources: Fundamentals of Heat and Mass Transfer by DeWitt et.al. Thermodynamics: An Engineering Approach by Boles & Çengel 5) Real-world example: compare the Noctua NH-D15S vs the NH-U14S desktop CPU coolers. noctua.at/en/nh-u14s/specification noctua.at/en/nh-d15s/specification The U14S has a single fin stack and single NF-A15 fan. The D15S has two of those same fin stacks, sandwiching the same fan - we effectively have 2 fin stacks in series. In the U14S, the air entering the single fin stack is ambient temperature. In the D15S, the air entering the 1st fin stack is ambient temperature, but when it enters the 2nd fin stack, it's much warmer. The ΔT for the 2nd fin stack is smaller, which means it itself has slightly less heat transfer, but the addition of another fin stack outweighs this difference. Indeed, the D15S (or D14S) outperforms the U14S, and similarly, the D12L (1 fan 2 stacks) outperforms the U12S (1 fan 1 stack): noctua.at/en/noctua-standardised-performance-rating aphnetworks.com/review/noctua_nh_d15/temp2.png More heatsinks in series is similar to having a bigger heatsink. Because there's more hot surface for air to flow over, the heat exchange is more "thorough". The gains are diminishing because of boundary layer effects and others, but there are gains nonetheless. I no longer have this laptop. All the information I have is on bradshacks.com/matebook-x-pro-throttling/. In the "Run Heatpipes to the Fan" section, you'll also find a photo of how Huawei themselves made the fan casing a heatsink in the later-released Honor Magicbook. The MateBook X Pro 2021 also does this: www.notebookcheck.net/fileadmin/_processed_/a/4/csm_MG_3155blur_1a09813f9a.jpg

@@BradsHacks I have to sincerely thank you! Your proof seems valid to me. You made in few lines a lesson about thermodynamics. Maybe mine was a useless question, I should have looked on the manuals: however, my course in physics did not go deep about heat transfer theory, so I have a difficult walk into. Now I have some reference books to solve my doubts. Maybe you are a mechanical engineer student? T3a should be higher than T3, because the added heatpipe increases thermal conductivity from CPU to fan case, than more heat is sucked away from it, similarly to resistors in parallel in a circuit powered by a current source. T3a would be equal to T3 if, and only if, the heat carried away from CPU is unvaried. About the overheating issue on my laptop, I compared it with a newer laptop I have, and the difference, apart from fan airflow rate, is in the CPU silicon die size: the older one measures 1.5 cm x 1 cm, whereas the newer measures 2 cm x 2 cm; that's actually a great decrease in thermal resistance! So, I can conclude that the heat bottleneck in the older pc is caused by the die size. Adding another heatpipe on the fan heatsink, as you did, can effectively help reducing the aggregate thermal resistance, as you proved. Finally, I read about the mod you did on your website, after seeing your video, but from that point some other questions arose to me: I would appreciate if you can help me solve: 1) Why is it mandatory to put thermal paste on the interface between the heatpipe and the underlying surface, given that the thermal paste will dry out over time? Why not just use the thermal glue to contact? Can you advice me a reputable product or can I get away with anything aftermarket? 2) How should I contact the heatpipe to maximize heat conductivity? Maybe maximizing contact surface both on the original heatpipe and the fan case? Again, thanks for your explaination; I have now a model to use for drawing conclusions.

Yes, but keep in mind your seats will not have airbag functionality if you do this. I'd rather hot-plug the airbags than do this. The airbag connector has a built-in protection mechanism against accidental discharge. The risk of not having airbag is bigger than accidental discharge.

Edit: It ended up being very beneficial as my printer is now fully a Mk3S except for the Y axis which is still Mk2 but with the removable bed. I can't run a calibration without modifying the firmware to account for the 10mm less z height, so it's good to know my printer is perfectly perpendicular and it doesn't matter.

The D15S has two of those same fin stacks, sandwiching the same fan - we effectively have 2 fin stacks in series. In the U14S, the air entering the single fin stack is ambient temperature. In the D15S, the air entering the 1st fin stack is ambient temperature, but when it enters the 2nd fin stack, it's much warmer. The ΔT for the 2nd fin stack is smaller, which means it itself has slightly less heat transfer, but the addition of another fin stack outweighs this difference. Indeed, the D15S (or D14S) outperforms the U14S, and similarly, the D12L (1 fan 2 stacks) outperforms the U12S (1 fan 1 stack): noctua.at/en/noctua-standardised-performance-rating aphnetworks.com/review/noctua_nh_d15/temp2.png More heatsinks in series is similar to having a bigger heatsink. Because there's more hot surface for air to flow over, the heat exchange is more "thorough". The gains are diminishing because of boundary layer effects and others, but there are gains nonetheless. I no longer have this laptop. All the information I have is on bradshacks.com/matebook-x-pro-throttling/. In the "Run Heatpipes to the Fan" section, you'll also find a photo of how Huawei themselves made the fan casing a heatsink in the later-released Honor Magicbook. The MateBook X Pro 2021 also does this: www.notebookcheck.net/fileadmin/_processed_/a/4/csm_MG_3155blur_1a09813f9a.jpg
@@BradsHacks I have to sincerely thank you! Your proof seems valid to me. You made in few lines a lesson about thermodynamics. Maybe mine was a useless question, I should have looked on the manuals: however, my course in physics did not go deep about heat transfer theory, so I have a difficult walk into. Now I have some reference books to solve my doubts. Maybe you are a mechanical engineer student? T3a should be higher than T3, because the added heatpipe increases thermal conductivity from CPU to fan case, than more heat is sucked away from it, similarly to resistors in parallel in a circuit powered by a current source. T3a would be equal to T3 if, and only if, the heat carried away from CPU is unvaried. About the overheating issue on my laptop, I compared it with a newer laptop I have, and the difference, apart from fan airflow rate, is in the CPU silicon die size: the older one measures 1.5 cm x 1 cm, whereas the newer measures 2 cm x 2 cm; that's actually a great decrease in thermal resistance! So, I can conclude that the heat bottleneck in the older pc is caused by the die size. Adding another heatpipe on the fan heatsink, as you did, can effectively help reducing the aggregate thermal resistance, as you proved. Finally, I read about the mod you did on your website, after seeing your video, but from that point some other questions arose to me: I would appreciate if you can help me solve: 1) Why is it mandatory to put thermal paste on the interface between the heatpipe and the underlying surface, given that the thermal paste will dry out over time? Why not just use the thermal glue to contact? Can you advice me a reputable product or can I get away with anything aftermarket? 2) How should I contact the heatpipe to maximize heat conductivity? Maybe maximizing contact surface both on the original heatpipe and the fan case? Again, thanks for your explaination; I have now a model to use for drawing conclusions.
Hey Brad. Once the seats are removed and the dongles added could I later attach the seats back in place without having to connect the wires back and remove the dongles? I don't want to trigger anything as I will be constantly removing and reattaching the seats.
Yes, but keep in mind your seats will not have airbag functionality if you do this. I'd rather hot-plug the airbags than do this. The airbag connector has a built-in protection mechanism against accidental discharge. The risk of not having airbag is bigger than accidental discharge.
Oh, Good point! Thank you for the quick response.
you are the goat bro!!! I just got the same janky box resistor from amazon and had the same thought; that if it gets hit too hard airbags might fly. I was about to break out the calipers and make my own but i dont see a reason to reinvent the wheel. You made my car camper build in my Toyota CHR way easier.
extremely based
Hey Brad, because there are two seats that means one will need two rounds and two squares plugs each for the two seat? Planning on doing mine soon. TIA
Yes
We need more of these.
Hoping to do this for my Lenovo T530. Other configurations like the DGPU version and W530 have three heat pipes whereas mine has only one. Unfortunately the mounting holes above the CPU are different between one heat pipe and three heat pipe coolers
That's really impressive work! My plan is to get an AWD Hybrid Sienna and remove these seats to make it into a stealth camper. Well done Brad...kudos!
Hi, it would work with 2007 lexus gs? Or the better question is which one of the versions would work on the 3rd gs? The same as the ES? Thank you
I managed to do this with my Prusa i3 Mk2, believe me it was a lot harder with the threaded rod setup! Edit: It ended up being very beneficial as my printer is now fully a Mk3S except for the Y axis which is still Mk2 but with the removable bed. I can't run a calibration without modifying the firmware to account for the 10mm less z height, so it's good to know my printer is perfectly perpendicular and it doesn't matter.
