Do I need a GPU cooler if I'm going to overclock my GPU?

Solution


Why not get a GTX 1050/1050Ti? Essentially same price for better performance. Unless you're getting a good deal for a second-hand card.

You will be able to overclock it, by how much is probably minimal, as overclocking the GPU brings almost little to no performance gains depending on the card.

That GTX 750Ti does have a dual fan cooling system so it will be able to keep it cool, that is on top of the fact that it is a really cool and quiet card. But with it not having an additional power source I doubt the overclocking potential is major.
No you don't. An aftermarket GPU cooler brings little to no benefit to overclocking at all. If that is what you mean.

Your GPU should be able to handle a slight overclock, what card is it as that will adapt how your overclocking process will turn out.
 
Impossible to answer without knowing which GPU you even own.

Modern ones are unlikely to benefit much, but there are some HOT cards especially from AMD R9-200 series that were throttling down to temperature.

You can find the throttle temperature for your card and monitor it as well.

There are also other reasons why a card may fail an overclock. Silicon lottery for GPU is the main one.

*just FYI, but there are modern cards such as the GTX1080 that do throttle due to temperature which is why an Asus Strix cooler can produce better performance than the weaker coolers.

The after-market GPU cooler must also be BETTER than what the card comes with, and case cooling should also be adequate.

You can even rig up a SIDE CASE FAN if that's an option which can help.

The title doesn't really say it all. The case size matters. The GFX card matters. The PSU matters. Everything about your build contributes to everything else. Without a quality PSU overclocking isn't recommended. Without a CPU on par with the GPU a GPU overclock may be worthless. You may not have enough RAM. In a perfect build you may not need to do anything other than overclock. The GPU is smart and will increase the fan speed as the GPU's temperature rises. Some users opt for manual/auto control. They create their own custom fan curve with MSI Afterburner(or something similar) that's a wee bit more aggressive than the default settings. Others will lock their fan speed to a constant number such as 60%.


What do I ask myself when I OC? What is this OC investment giving back to me? Heating my house better? Not enough. There has to be a significant FPS change or other desired increase(benchmark score for example) for the OC to be applied and left there. Do you have a 60Hz TV or monitor(which can only show 60FPS) and regularly hit 100+FPS? The OC wouldn't help anything. Does your CPU regularly hit 90%+ during gaming? Your rig may be CPU bound negating any possible benefit a GPU OC could return.
 


Budget limitations :/ Although I will upgrade later on, but for now this one should be great. Thanks for the answers.

If it's important, I'll have a 550W power source.
 


Depending on the PSU, you should be good. The GTX 750Ti only requires 75W of power supplied through the PCIe lane. Do you have the exact model so I might be able to assist you depending on your upgrade path.

And budget limitations is fine, you could always keep that card as a backup. The 750Ti is a great little card for what it is. Should be able to run decent settings on 1080p, or better settings on 720p.
 


Thanks man, cheers.
