How much temperature i can drop by using a dedicated GPU

[Sagar_20]

Recently i sold off my gpu to upgrade later and since then i think the cpu temps have started to rise up really high. Even though i am not doing any thing graphic intense i believe the culprit is the integrated graphics, HD 2k. I do not remember the previous results but these days the cpu is averaging at around 45°C, at times even crosses 50°C, and the max i have seen was 67°C. What's your opinion on this? Would switching to a dedicated graphics card help the cpu run cooler?

What CPU are you using specifically? I cant think of anything remotely modern where those temps would be problematic.

That being said, generally speaking yes, using the iGPU (or hyper-threading etc) would see the CPU run 'hotter' overall, than when those are not being utilized. Not 100% on specific numbers, but I'd imagine the variance is in the <5'C range.

67'C max, for most CPUs is totally safe and I wouldn't worry about it.


Yes, a dedicated GPU would likely see the CPU run a little cooler but, if you don't *need* a discreet GPU right now anyway, I wouldn't worry about it.

I am using a Core i5-2310, so no chance of hyper threading but im worried heat can possibly affect its life expectancy? I have no problem with a dedicated GPU. I removed the old one only to upgrade.

Heat can certainly reduce lifespan of electronics, but that relates to "high" temperatures. Operating within normal spec isn't going to cause an issue.

For an i5-2310, the throttle temperatures is around 95'C IIRC. "Safe" operating temps would be <80'C, ideally lower. If you're not even seeing 70'C at it's hottest, you're perfectly fine.

Intel CPUs can run reliably right up to their rated 100°C maximum safe core temperature. They automatically slow down (throttle) when they reach this temperature to prevent any damage. No worries.

Depending on the Gen, they'll throttle before 100'C.... and shutdown hard at ~105'C IIRC.

The TCase for that chip is 72.6'C as per Intel themselves:
https://ark.intel.com/products/53445/Intel-Core-i5-2310-Processor-6M-Cache-up-to-3_20-GHz

Which is typically around 10-15'C lower (Depending on the cooler... and other factors IIRC) than any monitoring software will give you.

So the max 'safe' operating temp of that chip would be somewhere between 80-90'C based on that rough calculation.

Sure, the CPU will throttle within that range, and harder as temps go up (to attempt to stop the temps climbing), but at 100-105'C, it's shutting down.... it's not "They automatically slow down (throttle) when they reach this temperature"
