M15x internal fan mods?

Also did you end up checking if your m15x has the EDP connector?

 

Not yet, I will find some time to take the laptop apart this week though.

 

Install of the M4700 fan went well. You can simply pop off the M17x R1/R2 stator from the metal shroud with standard screwdriver by prying up. Slides off the bushing and you can rip out the metal bushing from the metal shroud with pliers. I opted to use a dremel and remove the metal "hump" and enlarge the mount hole with a drill.
That allowed the 6 stator to mount flush. I carefully used wire snips to remove all the plastic from the M4700 stator, well not that carefully since when I originally was using pliers I broke a trace and had to bluewire fix. Then transferred the M17x fan wiring matching the yellow, blue, black then red of M4700 and hot glued the whole unit to the metal shroud. Exact fit.

Neat that whatever RPM is commanded from the EC should result in nearly double the CFM (old 5 cfm vs new ~10cfm on fan)

 

more importantly, how are temps now compared to the old fan?

 

With my y510p if I let the EC control the new fan it resulted in higher temperatures. I think it was because on my laptop the laptop would have a temperature to RPM curve instead of percentage.

Just something to consider if initially things to pan out for the better.

 

Oops probably should of done a baseline. I was able to move from 24 to 25 mult on CPU in throttle stop for 4 cores. Gaming on Fallout4 did not result in normal stutter in cities but I also was able to bump up the GPU since I redid the paste with the bear krispynaught (or whatever it is) on both the CPU and GPU

I think there is no room to glue the plastic onto the metal shroud. Need to cut it out and sink it in. Or I guess add washers which would cause crappy airflow IMO.

Later had to press on the shroud to get slightly more clearance, again no room unless sinking fan into the metal and grinding down the metal hump.

24x multi is stable under normal fan I found. Yes temperatures stabilise at about 96C but who cares the chip is good for up to 100C before the system hard shuts down while throttlestop still extracts max load at those temps. Hardy chips the mobile Nehalem.

 

Mine just goes to like 72*C during TS bench, 96*C seems kinda hot.

 

TS　bench is a fairly light load. I was using handbrake to encode videos for 14 hours straight at those temps at 100% load back in the day

 

They just don't make loads like the used to.

 

72C is quite good for 25 across all cores, I was getting around 80c for 23-24 on the TS bench.

 

If someone else can install the M4700 fan we can check multiple systems.

 

i tried the m6600 fan and it physically will not fit in the CPU side. i dremeled as much as i could out and it wasnt going to happen.

I then modded in the M11x fan. the MB controls the speed but my 920xm throttles and stops at 15x. every setting is correct in TS is fine. i gave up and ordered a 7.7cfm fan from ebay complete with a new heat sink

 

so i guess the new TS is not happy with running on the m15x. reverted back to 7 and the laptop happily went to 24x

my temps were worse with the m11x fan than the stock 5.5cfm fan

new 7.7cfm fan came in and i can tell it moves ALOT more air than the M11x was

my temps are now a reasonable 75c while playing destiny 2 at 25x on 4 cores
