My ongoing overheating problems-faulty sensor?

Hi. Posting this here as I'm not 100% sure it's a mobo problem.

My spec is in my sig.

When I first built my pc my cpu would randomly overheat say every 10th boot and only sleep/wake or power cycle would sort.

I finally realised that a permanent solution seemed to be to set the sys fan to full speed in bios to make sure my pump was always running (pump was found to be running much slower than it should).

All seemed fine until I realised that sleeping the pc now brings the problem back. The problem is effectively reversed and only a restart sorts it.

When this problem occurs, what AIDA labels as cpu (this is incorrect, it's not any core or package, HWMON labels it as tmpint0) shows -128c and the pump drops down to about 450rpm from 4500rpm.

It seems that the pump (or fan) connected to the sys header is being slowed down by a faulty sensor reading but it also seems like putting my pc to sleep is toggling the fan settings in bios...is there any way I can investigate this without booting into bios?

Tldr...can I see what fan profile my bios is running the motherboard at from within windows?

Thanks.
 
In HWMonitor the only thing I have that resembles tmpint0 is TMPIN0 and that's on the graphics card. -128 will be a faulty sensor or HWMonitor just isn't reading it right. Surely the pump should be plugged into the cpu fan header though and not the sys fan header?
 
TMPINO is for gpu temp here too in HWMonitor, identical values in gpu temps in afterburner. I thought theese pumps had to be connected to a fan header that supplys a constant 12v, not a PWM header like the cpu one?
 
Thanks. TMPIN0 I meant.

That's definitely not the graphics card on my board. The temp it shows seems to be about 5 degrees below package temp.

My H60 pump runs off a sys header fan but this is still controllable in bios.
 
I tried all sorts of different fans and the stock cooler last time.

I'm 99% certain it's not the pump but will test.

Can I ask exactly what you suspect?

Thanks.
 
Thanks.

I'm on f4 which was latest when I last looked.

My puzzlement comes from the fact that the system reboots and cold boots flawlessly but starts acting up from sleep (and did the opposites when the bios was controlling rpm) but never misses a beat in operation.

Starting to reconsider the psu again even.

So I took my pc apart the other night to test out with the stock cooler again.

I rerouted my sata cables and moved my h60 tubes a bit.

Turned it back on again and it's completely fine!

I have absolutely no idea what's going on here.

Wouldn't know what to rma but I want to sell this stuff on eventually.
 
I had a faulty h100
The water block was hot
And the tube with liquid that flows towards the radiator was hot as well
Cpu was struggling at 80 degrees
If the Cpu is really hot you should feel it :)
 
So here's a final summary of what's been happening with my ocassional very high CPU temps (I am on latest bios, 1.224 vcore, cooler properly seated).

1. Randomly every 10-20 cold boots my pump wouldn't work properly (temporarily cured every time by sleeping then reawakening. Permanently cured by turning the header controlling it to 100%) but...

2. After doing this, everytime I put the pc to sleep it would reawaken in the problem state...the exact opposite problem. (Permanently "cured" by faffing around inside my case last night).

I'm pretty baffled but if the problem doesn't come back again I'll sell it all in good faith.

I hate not knowing why these things happen though, would love to get a definitive answer.

It has to be the mobo imo.
