Lenovo IdeaPad Y700-15ACZ
So If many of you are not aware. The lenovo Y700 series is known for having a problem on all models. That is that the CPU throttles because a dust filter is blocking the majority of air from coming into the laptop vent system. This causes the cpu is reach very high temperatures. When the cpu is under load, rather than going from core clock speeds 2.1GHZ to turbo clock speeds 3.4GHZ, the cpu is overheating and cannot maintain a 3.4GHZ clock speed, dropping done to low clock speeds like 1.5GHZ to maintain ideal CPU temperatures. In other words, CPU Throttling. This causes gaming to be very frustrating because your FPS will spike up and down randomly.
My problem is that i have removed the dust filter that should be the source of CPU throttling, but running CPU-Z my clock speeds are still going from 3.4GHZ down to lower clock speeds like 2,5GHZ and sometimes 1,5GHZ. Everyone, and everywhere i have checked people have said that the dust filter fixed the cpu throttlings but i might have messed up somewhere else. My laptop for sure feels much cooler than before, and performance is a bit better but still up and down.
What i have Done:
So this is what i have done to prevent CPU throttling.

Thanks for using the Lenovo forums.
Have a look on the following posting on Lenovo, see if any of these steps could be of use.
Hope this helps, let us know how you get on.

Same here, waiting for a true solution from Lenovo (New bios, better fan curve, support for ddr3 2133...). Even with CPU undervolted at 1,22v this computer throttle, as Notebookcheck said "Lenovo presents a gaming notebook with which you cannot play computer games well in its current state". It's a joke.
The worst thing is that a good bios could solve these problems

If i could just lock the max turbo clock speed and force the fans to run 100% then i bet i would be able to resolve the throttling problem. Like rather than running at 3.4ghz and sropping to 1.5ghz just lock in at a stable 3ghz or 2.7ghz so it doesnt over heat. But lenovos bios doesnt let u do anything.
