Will using Intel's integrated graphics increase temperatures?

[TheAJ]

Hi,

I recently assembled a PC to get some hands on experience. I resolved most of my questions via searching Google (most of them were solved on this forum), but could not find a definite answer to my latest question; will using Intel's integrated graphics increase my CPU core temps?

I have a 4770k, but my question is generic towards all CPUs that have integrated graphics.

If I install a graphics card, which will (by what I understand) offload some operations to the GPU, will I see improved temperatures on my CPU?

At this moment, I do not have a graphics card (mainly to ensure that the rest of the system works and is stable before buying some extras such as the GPU, better fans, more HDDs, etc) so I am using the integrated graphics that comes with the haswell processors

My main use of this desktop will be programming/development.

I would suppose so as it requires more voltage to be consumed in the CPU.

Yes it does but the igpu is low power, 4w tdp, so it isn't much. You probably won't even see a difference.

Btw adding a graphics card doesn't offload some, the igpu gets disabled.

Installing a discrete GPU will indeed disable the iGPU as default, but you can enable it back via BIOS if you need it, e.g. if you want to connect another display or a TV set and your discrete GPU doesn't have the right port.
I too have a 4770k and just noticed that by taking out the discrete GPU (I had an Asus GTX 650 with 2GB DDR5), the CPU runs cooler at 25 - 35° Celsius, as opposed to 35 - 50° Celsius I had when the GTX 650 was installed and running.
And no noticeable difference in CPU temperature if the Intel iGPU was enabled or disabled.
