It Works!! M14x R1 fan replacement w/ R2 fan. MASSIVE improvement w/ temps and efficiency.

Recommended Posts

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”.

Not sure if you're still active on here or not, but I'd just like to ask, have you done anything else since this? I've been thinking of doing some kind of heat sink mod, because the temps are just horrid. Hope you get back to me, and thanks for the idea!

Hey my man! Sorry for the super late reply, but no I haven't really done anything else as of yet hardware wise, but its been running great with the software and bios tweaks I made.  You should definitely check into replacing that fan.  I'm actually about to add some thermal pads and repaste, just for maintenance sake.  Good luck!  Message me if you need tips

Hey, quick question; my R1 also runs pretty hot, but all the replacement fans I've been able to find online don't really specify an air transfer rate.  Do you know of any way to tell the difference between R1 and R2 fans?  If not, do you know of somewhere specific to get the better R2 fans?  I've been searching eBay and Amazon, and only found the individual fans with no way to tell if they are the better quality ones.

Yes, the R1 fan has 2 CFM (cubic feet per minute, I'm assuming) while the R2  fan has 10.4 CFM.  The R2 fan has smaller blades that don't begin until the outside edge, and are more finely packed together, like a jet turbine.  The R1 fan has conventional paddle blades that extend all the way from the center to the outside edge, and there is more space in  between blades. 

 

Good luck! Let me know if you have other questions. 

 

Edit: found a pic of the R2 fan, notice the blades don't begin until the outer lip of the fan

lemme get this right , 

 

M14xR1 OEM Fan = 00H8HD ( DC280009OF0 )

 

1.jpg.b420502e49b667367e5d886c301d6cb7.jpg

 

M14Xr2 Fan = XN0G5 (DC28000AJF0)

2.jpg.e127057590c9034d8c91df990761baba.jpg

 

 

 

after some research, i confirm that the

R1 00H8HD Model has 2 cfm (low airflow)

R2 XN0G5 model has 10.4 cfm (5x the airflow)

 

 

i'm buying the XN0G5 as of now , thanks man !!

 

will keep you guys posted !  Jan-2020

 

(also i'm looking at DC28000CGF0   for the R3 variant )

 

 

EDIT AS OF Oct-2020

 

so i just installed the R2 model Fan and it's way better than the R1 

Totally worth it !

I was also looking to change my system's Fan. I was surprised to see that there are many system fans available these days. I was also confused which fan should I buy. But I think the cooling system of a system is very important may be because I am facing cooling issue for some time. Because of this issue by system turns off atuomatically without any warning.

      Hello guys 
       
      I've got a pretty weird problem with my M18x R2. I already searched the web but couldn't find an answer. A few days ago I changed some settings in the bios, if I remember correctly DMVT Pre-Allocated.
      After saving this setting the notebook refuses to even POST. I get no beep errors or anything. If I press the power button the system turns on, the leds turn on and then the system shuts itself off. I already reset the cmos, the IME, tested different configurations and so on. If I remove all the memory sticks I actually get the memory error code. At this point I'm pretty sure that the bios got corrupted for some reason when saving these mentioned settings. Did anyone had a similar problem and got a solution for this? I repaired lot's of notebook but never had an error like this...
      The Bios installed is the a15 unlocked.

      Okay here is what's going. I have a alienware m18x r1 running an amd 8970m, I wanted to upgrade it to crossfire but I could see a 8970m was more expensive than a r9 m290x
      So I decided to buy a r9 m290x and see if I could make it work in my alienware and also run crossfire.
      Even though many shops refused to sell me one because the didn't think it would work in an alienware m18x r1 only in the r2.
       
      Here is the whole process.
       
      19/08/17 23:15
      No post bios showing when booting, so impossible to enter bios menu, but can boot into windows 10 with no problems.
       
      19/08/17 23:20
      Because I haven't deleted the old AMD 8970m the r9 m290x shows as a 8970m with no problems.
       
      19/08/17 23:34
      First performance test was a success. The r9 m290x changed p-state normally. The gpu fan start spinning normally. But because of no thermal paste, the test lasted 20 seconds because the temperature raised fast.
       
      20/08/17 00:00
      Created a backup of the vbios version
      015.032.000.004.044450
       
      20/08/17 00:10
      Flashed a new clevo vbios version 015.032.000.003.044465
      Caused the card to be corrupted and resulted the 8 beep code.
       
      20/08/17 00:35
      Finally managed to flash the back and return the graphics card to its original state.

      20/08/17 00:50
      Flashed a new dell vbios version 015.046.000.014.045579
      No change in behavior
       
      20/08/17 01:07
      After trying multiple vbios with no luck I finally found one.
      Dell vbios Version 015.041.000.000.044966
      Brings back the post bios screen and I can now enter the bios menu through the r9 m290x.
      Note: This vbios reduce the cards performance from 900 mhz to 850 mhz
       
      20/08/17 01:21
      After more testing I found one that is working with no limits.
      Clevo vbios version
      015.036.000.005.044618
      Brings back the post bios screen and I can now enter the bios menu through the r9 m290x.
      This will be the vbios I will keep at the moment.

      20/08/17 01:56
      I completely uninstalled the previous driver and installed the newest driver. The graphics card is recognized as a 8970m but works normal.

      21/08/17 20:15
      I have inserted my old 8970m in the secondary slot and will start testing crossfire.
       
      21/08/17 21:45
      I have found out that the fan for the secondary fan did not spin. The is a cable that have felt out. I will fix it now.

      21/08/17 22:00
      In my try to test crossfire compatibility, I installed the newest AMD driver 17.7.2 but as soon it installed the driver for the secondary card it caused black screen. Only booting the computer in safe mode brings the screen back.

      21/08/17 23:02
      After many frustrating hours I finally managed to get crossfire working with the r9 m290x as the primary card and my old 8970m as the secondary.
      I have flashed the same vbios on both cards so the r9 m290x shows up I device manager as a 8970m.
       
      I first installed AMD driver version 16.2.1
       
      Then installed AMD driver version 16.6.1 in order to play battlefield

      21/08/17 23:20
      First test run in battlefield 1

      21/08/17 23:40
      Battlefield 1 is flickering bad, this can maybe be solved with a new patch or driver.
      Other games I have tried is working perfect with crossfire on.


      Now what I would like to try is somehow force the r9 m290x driver to be installed and see if it will make it possible to run the latest AMD driver without getting a blackscreen.
       
      I have tried to edit the .inf file like you would do with nvidia but no luck.
      I have also tried to figure out how to edit the device id in the vbios, but I find it too complex.

      i want to ask two favours and a question from this community ..
       
      1.) Can someone mod my 940 mx to increase the target temperature and allow higher overclocking than 135hzband voltage control
       
      2.) Allowing my i5 7200U to be undervolted to reduce overall heat 
       
      The question : I repasted my gpu and cpu cleaned it thoroughly, made sure twice everything is connected properly, use a cooling pad and yet the upper portion of my chasis above f1-f12 keys is so hot that i can roast peanuts on it. 
       
      (if i left out any info or missed something please reply i would really love to have a page that has everything for people who have this laptop specifically for light gaming.)
