No problem, you could also try just tweaking my script to suite your program. Find all "Energy Management" instances and change them to "Energy Manager". There is a good chance the hidden button name is the same, "DustStart". If it also shows an "OK" button at end of a normal cleaning cycle, it should work just fine. Good Luck, let me know how it works out either way.
PS, I am working on another version of my original script that runs the fans for longer intervals = more cooling. When I have enough free time I will post an update.

@kramer46 Thank you, I used a Dremel tool with the sanding drum and then I switched to a high speed cutter to get into the tight spots. (pictured in spoiler)
If you take your time and protect the finish with tape, the mod will be undetectable with the air filter in place.
This definitely helped with the UltraBay gpu temps! I was experiencing throttling while playing Battlefield 4 and after the mods this no longer happens. I could not believe how buried the UltraBay fan intake was, it's like it was an afterthought with little consideration given to cooling efficiency.
I did not record data before the mod because my original intent was to fix my overheating problems, not create a forum thread

Overall, I appreciate your effort at this mod.
I just wish that Lenovo does look at it and hopefully improves the future builds to provide more opening for the fans. I agree with your thought, the whole extra GPU in Ultra bay looks like an after thought and the least tested area by Lenovo.
Though it has improved with the new GT755m ultrabay implementation but still lacks the perfection.

FYI: I have a cooling pad and, without the pad I got temperature of 64/69 on a SLI config, CPU going around 52 to 54
With the pad (20$ pad with a fan), GPU is 56/60 and CPU goes from 42 to 46.
OEM SLI config with dual 750M, 128GB SSD, 8GB
Temperature where optained right after running 3dMark

@t1mman I usually don't check temperatures using this method. The problem is that temperatures can drop quite a bit immediately after heavy load. by the time 3DMark has completed and you check your temps, they will be lower than what they were during load. Use monitoring software that graphs your temps over time. This will allow you to go back and see how hot your components really get during load and help you make more informed decisions about graphics settings and cooling efficiency. I use MSI Afterburner to monitor my gpu temps and real temp for cpu temp.
Immediately after testing my gpu tems were 46 and 48. My CPU temp was 54. Looking back, just 2 seconds before, (during load) both GPUs were @ 58.
I like the idea of comparing temps, but we gotta make sure we are all on the same page. Lets post 3DMark scores just for fun too. (not 3DMark 11, I heard this does not push our system as hard as the new 3DMark)
Lets keep it legit, run without any overclock and post score (and temps if you want)
And here is a look at my temps at idle while I'm typing this:

@Erni3 thanks again.. i shrouded the plastic at the back just like yours. I am not sure how much of an impact it would be but I'm pretty sure it will have a positive effect. And the script you wrote for the infinite fan cleaning loop works really great. If you have the new script that you are talking about please share it to us. I really appreciate the work you have done. The ultrabay gpu temps are really a problem with me and with this at least I don't see some throttling anymore on the games I played. (Y)
