HWiNFO64 causing laptop to shut down...

A couple weeks back I started using HWiNFO64 to set a more aggressive fan profile while playing higher end games. Everything was working fine and dandy until a couple days ago when my laptop started shutting down the second the map loaded in BF3. I thought it was my overclocks, so I shut down Afterburner and booted back up. Same thing. This time I tried without HWiNFO64 and without Afterburner and things worked fine. After some tests, I found that having my custom fan profile turned on caused my laptop to power down as soon as any game loads up. Heat is no the issue, as it was powering down well below 70 degrees.

Below are some pics of my fan settings and my OC settings (in case they are important). I am running the modified A08 bios with optimus disabled.

 

Is your CPU heating up? Because the fan control is comtrolled by GPU temps. Which means CPU temps may rise loads without the GPU heating up at all which means the fans don't ramp up at all because they are overridden by HWiNFO64 to only ramp up when the GPU heats up.

 

Make sure you're using the latest version and use DELL EC instead of COMPAL EC.
To do this go to Program>Configure, uncheck "LPC & EC Support" and check "SW SMI". Then for your fan profile, use Intel CPU #0 as the Sensor and just choose anything for the Reading.
COMPAL EC has caused problems for nVIDIA cards (ATI cards seem to be fine). The downside to DELL EC is less precise fan control; it only gives you off (0 RPM) low (2400 RPM) and high (4000 RPM). However it should solve your shutdown issues.

 

This seems to be the case. I enabled all the sensors again to see exactly what is happening. When BF3 is loading up, the GPU is staying cool and the CPU temps keep rising until it shuts down at 99 degrees. How can I avoid this?

Edit: I haven't tried the above yet because I want to try and avoid constant max rpm if possible...

 

Have you tried using the CPU#0 Digital Thermal Sensor/Core Max as the fan sensor? Use the CPU temp to trigger the fan and not the GPU temp. My GPU temp is always lower than the CPU so I always use the CPU temp to trigger the controls on the fan rpm.

 

How bad is it if its screaming max the whole time I play?

 

4000 RPM is quite loud. If you use a head set it won't be a problem though.

 

Read the info in this thread and it should help:

Instead of using the Compal EC you can use the Dell EC if you are having issues with the Compal EC. Refer to the screen shots in the thread below for alternative configuration options you can try if you have issues with the configuration in the above link.

I mean physically for my machine, is it bad for it?

 

Puts more wear on the fans, that's for sure. Not sure what the MTBF for the fans are but most fans have a MTBF of around 30000 hours which is roughly 3 years straight. So if you were to run the fans for 12 hours a day you'd get just under 7 years of life out of them. Of course this is assuming the MTBF for the fans is 30000...it may be shorter than that given they're smaller fans and probably not the best quality.
