Dell M4600 Repasting

Repasted my CPU/GPU.
Used Shin-Etsu X23-7783D

I have suspicions I may be able to increase fan voltage by 30% without harming the fans.
Waiting to buy a couple replacement fans before I try though. Atm the replacements are expensive.

Specs:
i7-2720QM 2.2 ghz quad
16GB DDR3 1600mhz
Firepro M5950
500GB 7200RPM (SSD on the way)

Before temps pulled from my logs:
Stock Thermal:
Idle:
CPU: 62c
GPU: 59c
Load
CPU: 85c
GPU: 80c~

Artic Silver 5 applied to CPU CPU/Stock GPU 7/9/2012:
Idle:
50c CPU
56c GPU
Load:
79c CPU
78c GPU

Idle/very very light browsing.


Load temps:

 

Would be great to have before and after temps comparison but I guess it's too late

 

Added before temps

 

You increase the fan voltage by 30%? What's the different in RPM?

GPU: Overclocked 870MHz, 100 MHz
CPU: ThrottleStop Turbo:Multiplier Mode = 3020MHz

Currently my system running
Idle
46oC CPU (3398 RPM)
47oC GPU (3015 RPM)

Batman Benchmark
Min = 52, max = 103, Avg = 82 FPS
71oC CPU
64oC GPU

Been running batman with 99% load 20Min:
71oC CPU 3685 RPM
63oC GPU 4079 RPM

Afterwards:
CPU hit 79oC but then the fan kicked above 4000RPM, bring it down to 69-71oC

My system the fan is always on, but I'm happy to have the system cool. Though it's quite loud..

I've recently change the thermal paste on my cpu, with Arctic Cooling MX-4. I used a copper shim for my chipset. I have yet attempt to change the GPU thermal pad, as I don't have any good quality pads or tall shims.

 

I haven't done the RPM thing, waiting to get some cheaper replacement fans before I do the increase (going to borrow power from USB 3.0).
Well I tested the fan using a expensive multimeter, and air flow measurer.
I used a cheap air compressor to let loose 12 cfm.

Motor released no electricity which from what a pal told me means the motor can handle the extra power, and thus the RPM. It's whenever it creates a lot of electricity that you can fry a motor).

Problem is you never know the long term effect (if the bearing can handle the extra RPM's or if the motor really will be fine). Hence why I want to get replacements, I am also waiting on my friend to let me know if the USB 3.0 could be used since it isn't native otherwise I can always pull power from the USB 2.0 for testing.

 

I do wonder what noise it will make with 30% voltage increase, cause over 4000 RPM is like a mini hair-dryer. But your temperature looks fine, are you going to attempt overvolt GPU?

I think there is a way to disable the Dell bios fan controller, and adjust fans by software. But I haven't attempt just read it from somewhere, where you have to go into Service mode. Sound like you going for extreme cooling, let us know how it goes.
