[SOLVED] core i7 3770 & 15 3470 HSF compatibility

[smtrejo]

Good day!!!

I own a HP Compaq Elite 8300 SFF with an Intel core i5 3470. I'm on a budget and I have the opportunity to upgrade the CPU to a Core i7 3770.

Is the current HSF (heatsink and fan) compatible with the Core i7 3770?

I've seen that there's a "round" shaped heatsink compatible with both cpu's, but mine is the "square" shaped version.

I've also read this post but my question is "inverse":

Thanks in advance

Physically, yes. Intel claims both CPUs have the same TDP, probably demonstrably false, but the CPU won't explode on you if that is what you are asking. Chances are pretty good they used the same heatsink for all versions of that system.

@Eximo, so the stock HSF will be sufficient to maintain the core i7 3770 temperature stable?

Yep, same tdp, so you shouldn't have any issues at all:

And as some food for thought, I have regularly put 95w cpus under 65w factory heatsinks and floored the hsf fan without any issues. It's amazing sometimes how much the stock units can take when all the fans are floored.

It should be fine. Even if it isn't, like I said, it won't overheat. The CPU will throttle itself if it is in danger of overheating. About the only thing that can damage CPUs are too much voltage, no heatsink at all, motherboard/PSU failure (lightning strikes, I suppose).

Basically their economy of scale makes sense to use the same cooler for a given platform. Easier to assemble, screw lengths all the same, etc. Not going to run out of one size cooler over another.

Intel releases their CPUs with CPU coolers of different thickness, reducing the height the lower the power. Since each model is sold separately the assembly only needs to happen at the factory making the coolers. Changing the line every few days isn't too hard and you have a 1:1 cooler to chip ratio.
