I have a Lenovo Y410P laptop with an Intel i7 4700MQ (HASWELL) CPU and a Nvidia GeForce GT 750M GPU.

The i7 CPU is a 2.4GHz model, but has a turbo boost feature which cranks up the power to 3.2GHz when needed.

When I check the CPU speed, using CPU-Z, it seems to be constantly at 3.2GHz. Which would explain some of the overheating issues I have been having from my GPU as both the CPU and GPU heatsinks share heatpipes and a single fan.

Is there anyway I can disable/limit the turbo boost feature of this CPU? I have checked the BIOS already and there's definitley no option there so I guess I'm looking for something I can run from the OS.

I have already stripped this system down, cleaned out the fan and heatsink and applied Artic Silver 5.

Any help appreciated greatly, as always.

Check your power settings:

High performance = highest possible turbo speed given TDP
Balanced = clocked low in light loads, high in heavy loads.
Low power = minimum speed maintained (800mhz usually)

That seems to have sorted it, thanks. Hopefully I will be able to cranks up the graphics a little now without too much extra heat.

I don't know why it was set as High Performance by default though!
