heated cpu

[Method-Man]

found out they way to undervolte! just me being a dope, I changed it from 1.712v to 1.690v already a big difference, been on stress for 15mins max 74 degrees but after half hour 3 cores went abouve 83degrees!! so shall i keep going or no its fine as it is?

Keep lowering the voltage until the CPU starts to complain (blue screens etc) and then bump it up by a couple of notches and run at least a 12 hour prime stress test. Then you have just about found the lower point of your vCore. There are other voltages you can lower too, but the vC is the main contributor to heat. As you can see it has already yielded results.

You can also try a reseat of the cooler if you want to, but like I said its 99% not the problem here.

@Albert - if you have that CPU running at those temps without a delid or undervolting, you have found yourself a CPU gem. The whole 47xx range are notorious for heating up into the 80s and 90s on stock speeds. There will always be odd CPUs that outperform their counterparts... I think you're morally obliged to overclock the thing ridiculously now


Edit - and no do NOT use arctic silver for a delid. If you are happy with the temps after some undervolting, don't do a delid. If you do want to, thoroughly read up on the subject before you do, like I said 1 wrong move and you will brick your CPU... nice new (very light) paperweight.

The other thing to remember is that too much AS5 (or any other thermal compound) can cause these type of high temps and variability (much as Albert suggested).    The idea is to use a seriously small amount, if you put on as much as a pea then you put too much on.   Use little and spread it out, a little goes a very long way.   I use a credit card to spread mine and I reckon I use about a quarter of a pea to do my CPU.

Marrowfat or petis pois?

There's an opening in the market for someone to manufacture cooling paste ready spread on a patch.

Maged to got to 1.660 now gunna stick with it as all cool temps max was 70c

[Chaosphere]

If you're getting max of 70s on a stress test, likely it will be in the 60s or even 50s when gaming - these are good results, means you actually have a pretty decent chip there (see what I said to Albert!).

It also pretty much confirms there is nothing wrong with the heater or the factory TIM... you can replace with your own AS5 or whatever if you want but I doubt you will see much of a difference.

I think a big issue with the 47xx chips is a combination of crap TIM between die and IHS, and that the overvolting by motherboards at stock causes ridiculous temperatures. If you can fix either one of these, you can sort out the temps. By undervolting you sort out 1 of the 2, and don't need to put your CPU near a vice and hammer. I did both, and then overclocked mine from 3.9 to 4.8... but that is only because I like the challenge of doing so.

So basically my thermal paste arrived to day I applied it and now My pc does not work everything has power but all I'm getting is a black screen,no bleeping nothing ,,(ties noose)

Ignore that the moment I pressed enter on my phone she woke up its all good
