Question CPU AT 70C IN BIOS

[Braddersc]

I had an i5 4460 which ran at about 30-35 idle and 70 when running games which is fine. I then installed my new i7 4790 and it was super slow. I checked bios and it was running at 90c so I imediately turned it off and resintalled my i5 4460. Now this is running still at about 70c when I’m bios. Please help. I’ve tried 2 cpu stock fans and have ordered a hyper 212 eco which comes in few days

With both instances what sort of thermal paste did you use between the cooler and the CPU's IHS? You forgot to mention the make and model of the motherboard as well. better yet, list your specs like so:

I think there is some sort of issue with the cooler.
I would check to make sure it's not loose.
There may also be something wrong with the fan motor.
I would also be in the BIOS checking the fan curve and seeing what I could get from that.
Being that you changed the CPU and the problem occurred....is why I think it's the cooler.

Improper installation of Intel stock cooler.

After removal of Intel stock cooler, push pins need to be reset before you can use the cooler again. If you don't do that, result is poor contact between cooler and cpu. Also thermal paste needs to be reapplied before re-installation of cooler.

Yeah I thought the cooler too but I have refitted it like 5 times

I

also Stefan rpmto max

Also set fan rpm to max

I really don't think it can be much else. If it's snug....I would think the fan isn't spinning fast enough.

Being you didn't have this problem before....I wouldn't think it would be the case cooling.

I think it has to be the cpu cooler and me fitting it but it doesn’t make sense. I’m also going to buy more thermal paste

is the 4790 identified correctly in the BIOS at power on/self-test display? (Everything CPU multiplier/voltage related set to 'auto'?)

You might need to clear CMOS, and/or, do a repair install, as Windows device mngr sometimes gets confused after doing CPU swaps...

Nothing you can do but wait for the hyper212. There's no way the stock Intel fan for the 4th gen i5 is going to be anywhere near effective enough for that i7. That's a 100w cooler on a cpu that'll hit 105w stock. Expect it to hit in the 90's gaming and throttle/shutdown if you stress with Prime95 small fft.
