No need to make a new thread... my info wasnt correct. The temperature raises now at the 3rd day of using the "new designed heatsink" slowly to the same temps as before. Looks like it was only at the first day when the temp were lower. Actucally i can see 94 degree celsius but 89 at the first day of the heatsink replacement. So i doubt its a new design - they just lied to me to calm me down when i was raging about the extreme heat my laptop produces. :/ Also when i asked them now why the temps are raising again every day they dont want to know anything about a "new designed heatsink". They cant remember ever telling me about it. Now i will get a mainboard replacement of the same type but as they say "better cooling performance"... I doubt it is the truth. Sry for the confusion.

Recently Dell created an improved Heatsink for the M14X which may be another reason why the R2 is cooler than the R1 additonally to the cooler CPU. They changed my Heatsink to the new variante (which looks very similar) and my temperatures are now down to 89 degree celsius (98 degree celsius before) under heavy workload (CPU and GPU max usage). Its still throttling cause of the 85 degree throttling limit but when only playing games my temperatures go max to 83 degree celsius which is below the throttling limit. The GB support technics also told me that there is a new mainboard mod for the R1 which also reduces the temperature. It could be a voltage mod or integrated heatpipes who knows. When i get my mainboard replacement i will post you my new temps . hopefully there will be no more throttling when rendering and playing games for example. Sry Mumak couldnt find the proper thread. Could you post us a link?

This sounds like an interesting idea. Do you know if it would be possible to exchange the heatsink and if so which one would fit into the chassis? I would offer to post my results after modding my M14x with an alternativ heatsink.

I totally agree that the actual fanspeed table of the M14x R1 should be like you said. But the fan noise is so disturbing at these speeds ~5600 RPM that they made the fanspeed table more like the users wanted it to be and that was more quiet and therfor more heating up. And to be honest i prefer less performance but the disturbing noise the fans would do if they start to kick in at ~5600 RPM at much lower temps.

I would be very interested to know if you can let Intel TurboBoost activated with the Ivy Bridge M14x`s without overheating till 100 degree like with the M14x Sandy Bridges when playing Games or using both CPU and dedicated graphics. Cause thats the main reason for all the needed! fan modding with the M14x R1. Even when only using the CPU at max workload the temps run near the 90 degree limit (M14x R1) and only dont go higher due to the throttling at 85 degree which decreases the clockspeed to cool the system down a bit to stop system shutdown or damage. The dedicated GPU is not the problem at all - it only goes to around 65 degree at max workload and therefor is relatively cool. The CPU is the problem in the M14x R1 - or better to say the cooling management of this CPU in this system is. But even there have to be some M14x R2 users around i cant find more than 1 very unspecific posts about the temp behaviour of the new M14x R2 under heavy workload and with activated TurboBoost. Im just curious.

Hm interesting. I will test how it works with disabled monitoring options. I need to setup something first cause of the bluescreen hangups to prevent damage. And yes the EC Compal fanspeed settings can have bugs at specific fanspeeds. Means it runs lower at some temps even when you set it to a higher rpm. Best would be EC Compal for the detailed possibility of different fanspeeds (1900 / 2900 are nearly not noticable cause of the accoustic frequency it produces f.e.) but it also cause dangerous lockups and BSODs. Most stable and easiest solution would be to fix the Dell EC mod so it runs at the 3 fixed fanspeeds but with different low and high fanspeeds we can manually adjust. I found out that the problem of the modded Dell EC is that is has no steppings at all which causes I/O errors and therefor BSODs whatever the concrete reason may be... The original Dell EC in fact has more than these 3 Speeds 0, 3000, 5000 as the mod has (in A08 for sure). It has slight steppings around these fixed Steps of (in fact 2100 / 3100 / ~4800 <-not sure on this). It increases and decreases the speed relative slowly at my A08 Bios so its not instant at the 3 fixed fanspeed unlike the Dell EC mod of HWINFO. And thanks for the throttlestop infos i might try this workaround!

Of course im using HWINFO for fancontrol but its very unstable and incompatible with M14x. The EC mode produces lockups and freezes and the Dell Factory Mode with the only 3 fanspeeds 0, 3000 and 5000 at A08 produces extreme high latencys, so every applications hangs for about 1 sec every 5-10 seconds - thats very annoying. The only use for HWINFO when it comes to fancontrol of M14x is when im surfing, chatting or reading i can set it to the EC mode as long as i dont use any CPU intense applications or i get the lockups/freezes. When i want to start a game etc. i have to manually set EC to none off then set to system auto to prevent any lockups/freezes. Thats the best workaround yet. Anyway this is a bit complicated it helps to make my 2 Alienwares very quiete when temps are only at about 50-60 degree with low workload. Hope these infos help you Pros to advance your nice tools for us thankful Users .

I also dont want to wreck my lovely Toy :<. edit: and yes i crafted some feet for it so it has better airflow below 4 cm at the backside and 3 cm at the frontside - but it only gives me about -5 degrees.

First i have to thank you svl7 for the nice work youve done and that you shared it for free! But i cannot get the fanspeed mod to work in the unlocked A08 BIOS. I tried to change from 55 degree to 60 degree for low fan speed and 70 to 75 degree for high fan speed. But when i monitor the behaviour of the temps and fans in windows with hwinfo64 it still remains at the fixed rates of DELL. And yes i saved my BIOS settings and restarted some times but still no effect from the BIOS mod. Any idea why that is ?
