CPU temps way too high, and wildly inconsistent

Last response: in CPUs
I installed an i3-4360 a couple days ago, but just thought to check temperatures today. They're not good, but thankfully I haven't been using my PC much, so damage should still be negligible. I still need to figure out what's going on and get it fixed before I do anything else though.
HW Monitor puts my CPU at about 30c on idle, which sounds about right. However, Speedfan puts my CPU at 15c on idle, which is obviously wrong as it's way below room temperature. Speccy is putting my CPU temperature at 35 idle.
Additionally, HW Monitor is putting my motherboard at a constant 118c, but it's obviously not that hot, because it's locked at 118c no matter how long or short the PC runs, at any load, and 118c should be crashing the PC. Also, the motherboard temperature is 20c in the BIOS.
When I run Prime 95, my CPU temperatures on Speccy, Speedfan, and HW Monitor all go up to 90-100c in only 2-3 seconds, which is clearly unsafe and would damage the CPU if I left it run like that.
It's worth mentioning I only ever feel cool air coming from my PC, but I'm not going to leave it running under load for long enough to actually let the whole thing heat up, if the temperatures are really that high.
Any ideas what this could be? I'm using an NZXT Respire T20 cooler, which people online said would work with the LGA 1150 socket, though it's a discontinued model and doesn't officially list LGA 1150 compatibility. I'd assume it was the problem, but It fits firmly though and covers the CPU, so I don't see how that could really be the issue. I'm using about the same amount of thermal compound I was on my Phenom II, and that stayed always between 30-45c.
I intend to test the stock cooler right now and see if that normalizes the temperatures. I'll post the results back here. Until then, any ideas?

I've seen HWMonitor, SpeedFan and Speccy all give wrong results.I Like HWInfo.
But the most reliable results come from bios - via your UEFI.
Either post results from Bios or Download HWInfo and run Sensors then post CPU package results.
Well, temps are normal until I stress test, so posting from the BIOS wouldn't help anything. But I'll download HWInfo and try that.

I ran HW INFO. It's putting me at 33c idle and 80c after a few seconds of Prime95. I'll post the CPU package results as soon as I figure out how to do that? Do I hit the start logging button and post whatever's in that document it creates, or is it something else?
Also, switching to the stock cooler delayed the heat-up by a few seconds, but did not fix it, so I guess the Respire T20 wasn't to blame.

When HWInfo starts up just enable Sensors..But if it's already posting 80C then I believe it. I gather your mobo doesn't use a UEFI?
Try the old stock cooler.
I use an Asus H97-Plus, so it should. Probably. I haven't been in the bios much, really just to find the C6/C7 sleep states.

You probably posted before I edited my other post. I tried the stock cooler, and it helped a bit but it still gets up to just as high of temperatures in a few extra seconds.
I should mention - I may have locked down the Respire T20 too tightly the first time I put it on. Could that have damaged anything in such a way it would cause the temperature to do this, or if it had been damaged by pressure would my PC simply refuse to start?

You should've got uefi software with your mobo. See if you can load that.What cpu fan rpm?
What Vcore?
Well, I can enter the UEFI bios. Not sure how it'll help though. I reset the BIOS to defaults in case something got changed, and the temps are behaving exactly the same afterwards.
According to HW Info, CPU fan RPM is at 1200.
Not sure about Vcore, the closest I can find is VCOREREFIN, and that's at 0.152v. Is vcore something else, and where can I find it? Thanks for all the help.

HWinfo should be able to detect the same sensor that the UEFI bios uses for CPU temperature, it would be listed under motherboard sensorsWould the "Nuvoton NCT6791D" be the motherboard sensor(s), or am I looking in the wrong place.
Hello, by the way. :s Hopefully we can fix this, or at least confirm what's broken.

Can you post the results from Sensors? usually 3 screenshots on TinyPic or similarDuring a stress test, or while idling? Sure, I'll make a Tinypic account.
Also, I'm not sure if it matters since I'm still not sure what the Nuvoton thing is, other than that a quick Google search talks about motherboard sensors. But the HW Info section under Nuvoton NCT6791D, in the CPU section, reached 37c at the same time all the other CPU temps were hitting 90c.

My i3-4360 runs hot too. It is what it is.100c after 5 seconds of testing is not normal. That's 20c above the throttling limit.
It's really unlikely that you can jump 70 degrees in 5 seconds with a correctly applied cooler. Sounds like a false reading or dodgy sensor.
do you have other sensors (i.e. CPU socket temps) that rise and fall more steadily under load tests? Look under nuvoton, that's the brand of sensor that your mobo uses. I'm with i7baby, a screeny of HWinfo 'sensors only' would be good.

Is this the right thing?
http://oi60.tinypic.com/wlw1v7.jpg
The Nuvoton CPU temp rises more gradually, though some of the other Nuvoton temps are still quite high.
This is a partial screen during Prime95.

The one marked 'CPU' under nuvoton is probably your socket temp, especially as you said it's rising and falling steadily. It's also in line with what I'd expect from a mere 54w processor. Also, your CPU is not throttling in that prime95 pic.

Both screens show your cpu at 100% usage and 88C - with or without Prime95
Nuvoton is at 25-37C which is OK. The nuvoTon NCT 6791D chip provides the super I/O functions, such as fan control and system monitoring
So I don't think either of your coolers are working - which seems incredible. The Respire - maybe a problem, but the stock cooler too? Seems too much of a coincidence.
The alternative is that the 88C is false.
Are there any symptoms of an overheated cpu? Does your pc seem sluggish? It looks like your cpu fan is speeding up. So my guess is that the coolers are not doing their job.
I think you need to get a cooler that definitely specifies lga1150. Something like the CoolerMaster Hyper 412 Slim. For an i3, it should be overkill. It's 160mm high. Will it fit in your case?
Do you have another cooler in mind?

Would it be safer to test my i3 in his mobo and see if it overheats, or to test his i5 in my mobo? Or both?
I'm pretty sure he'll allow it either way, as long as it's reasonably safe, but I don't want to risk my defective motherboard (if, in fact, the board is defective somehow) damaging his i5 or anything.
I mean, it seems like the options are either my i3 is defective and it's getting really hot, or my mobo temp sensors are defective and are making it look hot. Or, I somehow got 2 defective coolers in a row. I should probably test the CPU and board.
I'm not sure whether it's sluggish... I'm used to an AMD Phenom II 955, which was very slow, and it's better than that. But I've no way of knowing if it's operating at the levels an i3-4360 is supposed to in overall system responsiveness. I suppose I should run a benchmark and see how those scores line up to what a 4360 is supposed to get.
I don't really have a cooler in mind. My case is a reasonably large mid-tower (NZXT Phantom 410), so I'm not worried about space. I'll check the Hyper 412 Slim.

Tried Novabench. I found a test for a few i3-4340s and one i3-4360. A 4340 scored 482, and the other 4360 scored 489. My 4360 scored 494. Looks like the CPU is performing alright, though the usefulness of the test is limited since it didn't affect the temperature much.
Next I'll have to switch CPUs with my brother, but it'll probably be a few hours until then. Thanks for all the help so far.
