During idle, the temps stay around 40C for each core. When playing games BF4, WoW, D3, etc. I'll notice a temp spike up to around mid 80's. RealTemp and Core Temp have both reported this and when I do catch it in the act, it never stays up there for more than a second and then drops back down to low-mid 60's. I've never seen this happen in idle, only under a load. Hell, even the load doesn't get above 20% unless I'm running VMs or other resource sharing/intensive tasks.

Anyone have a clue of what might be going on? I haven't reapplied paste because I don't find that necessary as of yet and would like to use that as a last resort based off the fact the temps don't ever exceed low-mid 60's except for that one second that it spikes.

1) mid 80's are acceptable temps for temporary spikes, so you should not be *too* worried.
2) Haswell is known for it's very non-stable temps. i.e the temps in Haswell always keep spiking and changing.
3)How often do you see these spikes? Every few seconds or every couple of miutes?
4)Are you overclocked? If so this might be an issue with your overclock.

I am not OC'd, running stock. And this happens occasionally throughout the day. I'll reset the min/max temps and it might take a couple hours at most times for it to spike again. Good to know this doesn't seem to be a major issue.

In that case don't pay too much attention to it. Also because of Haswell's peeks it is more reliable to monitor the temperature labeled CPU (it's an average).

Alright, thanks a ton. Off the top of your head, do you have a temp monitor you recommend?

Intel XTU is great for monitoring everything. Since you didn't set a voltage manually, akso use this to monitor the voltages and make sure the peeks aren't a result of too high voltages. If you're under ~1.3 V (this is getting pretty high) you're good.
