How to disable bundled profiles in Rawtherapee

This has been bugging me for a while the way the drop down list of profiles to select from is very long!

The answer is to edit the text file called “options” located at /home/{username}/.config/RawTherapee

(you might need to enable “show hidden and backup files” to be able to view this directory)

There is a section in this file called “profiles” and you need to change UseBundledProfiles=true to UseBundledProfiles=false



When you restart Rawtherapee you will no longer see the long list of profiles as you will only see your own custom profiles.


Setting up a PWM profile for a CPU fan

I notice that it is possible to set up a PWM “custom” profile for both CPU fan and case fan on the ASRock H87 Pro4 motherboard.

The default temperature ranges are

50 degrees, 60 degrees, 70 degrees, 75 degrees with 80 degrees as a “max” temperature where the fan will run at full speed.   These threshold temperatures are can all be changed but I just kept them “as is”.   The 80 Celsius is fixed and the fan will always run at max speed (2000rpm for this specific fan) when this temp is reached to protect the cpu.

For some reason the 4 pin CPU header on my motherboard did not seem to work correctly in that the fan would only run at either 100% or 0% PWM, so I have plugged the CPU fan into the “chassis fan 2” header which works OK.

The cpu fan has a max speed of 2000rpm at 100% PWM, and I have found that 1200rpm seems to be a good “idle” rpm as this gives good airflow yet is pretty much inaudible.

I did a quick test to find the PWM % settings for intermediate fan speeds of 1300rpm, 1400rpm, 1500rpm, 1600rpm, 1700rpm and 1800rpm and got the following results:

1200 rpm ~ 66% PWM

1300 rpm ~ 71% PWM

1400 rpm ~ 76% PWM

1500 rpm ~ 81% PWM

1600 rpm ~ 86% PWM

1700 rpm ~ 91% PWM

1800 rpm ~ 95% PWM

I tried to find the PWM% for 1900rpm but this would have been somewhere between 99% PWM and 100% PWM and I can only work in 1% steps so was not able to record this setting.

I used these results to set my “custom” fan profile:

1200 rpm ~ 66% PWM – used for up to 50 Celsius

1300 rpm ~ 71% PWM

1400 rpm ~ 76% PWM – used for up to 60 Celsius

1500 rpm ~ 81% PWM

1600 rpm ~ 86% PWM – used for up to 70 Celcius

1700 rpm ~ 91% PWM

1800 rpm ~ 95% PWM – used for up to 75 Celcius

Here is the bios screen setting:


And a confirmation of the “idle” running speed of cpu fan up to 50 celcius


Film Archives

It looks like I have been quite organised with my scanning backups as I have found quite a few film shots that I took the trouble to scan, which were mainly taken in 2012 at some time.

These were taken with a Nikon FM2 and Pentax MX film SLR which are both fully manual 35mm cameras.

Legacy Photos

I have been having a look at some of the old jpeg photos on my hard drive and some of them date back quite a long time, as far back as 1998 in some cases.

This is one of the oldest shots and dates back to early 1999 when I first visited New York – Strange to think this building is now long gone.


This even pre-dates digital photos and I remember scanning the prints.


In this picture I am looking at the large mast on the other tower


This was a trip to Paris mid 2000 – I seem to remember I got my first digital camera about October 2000 so this is film.

Moving onto some of my first digi pics with a fuji mx1200


This is taken under the Humber Bridge – I lost a lot of original digital pictures and many of them were “rescued” from an old archived version of my website, but not full res versions and the exif is missing, but this would have been around 2001

A trip to Alton Towers, again  April 2002 – for such a basic digital camera it actually still took quite reasonable shots – I think it was 1.3 megapixels!

Italic Smile Theme

I have been using the “Sandbox” theme since starting wordpress at the start of 2013 but I was starting to feel there was simply too much white space in the blog.

There are a LOT of themes if you go to the “add theme” menu so I have tried the “Italic Smile” theme which seems quite good and still fairly minimalistic.

The homepage for this theme is

I like the way it deals with images, and it makes it easier than my previous theme to open, view & close images



How to save nvidia powermizer settings after reboot

This has been bugging me for a while as I notice there is now way to force powermizer to always use level 3 even after a reboot.

Luckily I found a handy youtube video showing how to do this simply by adding an extra line to a file.

Here it is:

It’s a simple matter of adding a single line of text:

Option “RegistryDwords” “PerfLevelSrc=0x3322; PowerMizerDefaultAC=0x1”

to the following file:


located at:


Please note that this line is added to the “device” part of the file


Section “Device”
    Identifier     “Device0”
    Driver         “nvidia”
Option “RegistryDwords” “PerfLevelSrc=0x3322; PowerMizerDefaultAC=0x1”
    VendorName     “NVIDIA Corporation”

The net result of this is that when you restart and look at nvidia-settings you get this:

and it stays on level 3
