Had to replace my motherboard recently, and my CPU temps seem to be fluctuating quite a bit in HWmonitor.
Yes I put new paste on. Should I give the paste time to settle before worrying? I've only used it for an hour or two after putting it back together, it isn't overheating or anything.

As long as you don't have a janky stock cooler you shouldn't have any problems.
Sidenote, are there any spergy programs that take up a lot of power and random moments? that could be it.
>paste settle in
This isn't a thing
re-apply the paste, make sure you apply it right though. Here is a good video showing how to properly apply thermal paste to a CPU.
Run a stress test and post results. Idle temps don't really mean anything.
here is the diagnostic tool you can use to run a test on CPU temps.

Not him but it used to be a thing back in the bad old days. You'd have to let thermal paste cure for a while. Needless to say, we've come a long way since then.
Temps actually seem to be stable now.
Temps will fluctuate until the whole inside of the case reaches equilibrium. It can take up to half an hour depending on how much thermal mass there is, how much heat is gererated, and how much cooling you have
Depends on where the program is measuring and what program it is. Core temps fluctuate very rapidly whenever there is a task being crunched, which is pretty much always, so you can see >5°C increases and drops all the time, but often the programs just won't register these spikes because they don't query often enough to notice them. If it's measuring in the socket, then obviously these spikes will average out and the readings will be much more consistent.

tell me MSI didn't make this...

Stop this meme.
You can definitely apply too much paste and it's messy and kind of dumb, but unless it's conductive there is zero chance it'll affect anything. The pressure of the heatsink will displace all of the excess. I actually apply a little bit too much every time so that I get 100% coverage even though a tiny bit will spill out on the sides.
this is a thing though
too much paste creates more of an insulating layer
thermal paste is just designed to bridge the gaps caused by imperfections in the surface of the cpu IHS and heatsink base
its not meant to be poured on there just to make sure theres plenty under the heatsink
if you have a layer of its thats too thick, along with making a fucking mess its going to be too thick for heat to be distributed efficiently
on top of that, too much paste may cause small air pockets to form, which while theyre obviously not visible with a cooler on, are there and are going to cause inconsistent cooling
for just covering the die on the pentium M in my t42, i used something like 1/8th of a grain of rice worth of AS5
>You can definitely apply too much paste
Sure you can apply more than necessary, but these people think it affects cooling.
You really that stupid boy?
>too much paste creates more of an insulating layer
The paste will take the path of the least resistance. After tightening, the amount that will remain between the IHS and heatsink will be constant regardless of how much you apply. You can drop a literal bucketload of it in there, and once you tighten the heatsink down then (given the same amount of torque), the layer will be exactly the same every time. The only way you can affect cooling performance is by applying too little, or getting insulating material between the surfaces (hairs, air bubbles, grease etc.)
Didn't feel like making a thread for this so I figure I'd ask here.
I've noticed my mobo even when I'm under high load rarely gets that hot, I don't think I've ever seen it hit 60c under high load.
Is that normal or do some boards run super hot?
>or getting insulating material between the surfaces (hairs, air bubbles, grease etc.)
Especially incompressible material.
depends on what the temperature sensor is on
if its around the cpu or below it, its going to change as the cpu gets hotter
if its measuring the temperature of the vrm's, its going to change as you draw more mobo power and it gets hotter, same for the chipset
The paste is to fill in the imperfections in the two metal surfaces. Metal conducts better than the paste, but paste much better than air.
So, use sparingly.
The paste isn't water. It has a very high viscosity and the springs used to hold the heatsink on are not strong enough to move the paste so that you have the same final layer thickness.
Too much paste is insulating.
>It has a very high viscosity
>the springs used to hold the heatsink on are not strong enough to move the paste
You don't understand how physics work. If the paste change its viscosity over time, which modern pastes don't, it will eventually move out of the way until a constant layer remains, regardless of the amount initially applied.
*doesn't change
By this logic every press in the world breaks the laws of physics.
Just delid the mothafucka and it's off to the races
temps fluctuating isnt an issue. what matters is how hot you're getting, and even then, sustained high temps are what cause damage.
just keep an eye on your temps and so long as they dont start shooting to the moon you should be fine.
