is it possible to overclock a graphics card on an un-overclockable motherboard and cpu?

cpu: 4690
motherboard:

I dont see the point in overclocking a cpu that is already effecient with the risk of melting your pc for a 0.2 fps improvement...it's always better to overclock graphics card and im guessing you don't need a fan for that? just more power? can someone correct me if im wrong and also what are your opinions on overclocking cpu, i find it useless.

Yes.



A CPU fan? No. If your GPU gets really hot, you may want an aftermarket cooling block for it.



That is a given.



More processing power. It's helpful to overclock the CPU when after years of using it, it becomes less powerful at stock. This in turn bottlenecks the graphics card. However, your CPU is not overclockable.

Regardless of CPU and Mobo you can overclock your GPU. No issue there.

When overclocking, more heat will be produced hence you would need a good cooling solution. "No fan" is not feasible and rather dangerous.

Overclocking CPU beyond its stock frequencies is always helpful in improving the overall performance and speed.

If your GPU is well overclocked but your CPU is at its stock and it could not be able to process the too much speedy requests from GPU then CPU will bottleneck the GPU in which case overcloking the CPU would be helpful.

4690 can't be overclocked beyond its max turbo.

Thanks.. so a overclocked graphics card doesnt require more psu? and about how many years until the cpu begins to lose power if you could estimate? :)

It definitely does.



Depends on what resolution you play at. At standard 1080p, at least a few more years. You just need to upgrade the GPU. For higher resolution, it'll be bottlenecking the GPUs. And almost no chance on triple monitor or 4K.
