Why is my PC still running this hot? (According to SpeedFan)

Jay Hamilton · Mar 14, 2014

Ok guys, this is my first post, so first, I'd like to say hello to the community and I look forward to discussing techie stuff with you!

First off, I'm not a complete noob or anything. However, I wouldn't consider myself a guru by far.

So, the problem that I am having is, according to SpeedFan, my "Temp3" is 85C (or in that range) and my Core temp is around 68C (or in that range)

I have already installed a ARCTIC Freezer 7 Pro Rev. 2 Heatsink (and replaced the thermal paste on it multiple times). I installed a 120mm fan in the front of the tower to intake air and the rear 120mm fan is the exhaust fan.

The specs of my machine are:
- AMD Phenom II X4 840 3.2ghz processor (not overclocking)
- 8gb DDR3 RAM
- NVIDIA Geforce GTX 650 1gb graphics card
- 1TB Hard Drive (don't think that matters)
- 400W Power Supply (I realize that this may be pretty low with the setup I have, but would that cause the CPU's temperature to rise?)

Oh and by the way, I've used the Arctic Freezer Pro cooler before and it worked wonderfully and definitely kept my temperatures well below the current temperatures.

So, to the point. My question is... Why is my CPU still getting so hot?

Edit: So, turns out my problem was that the Easy OC Switch was turned on on my motherboard

((. After buying a couple fans and a new power supply. Lmao there's my impatience working against me again. Well, guess I just made my computer a lot better than it was

speedfan is not so reliable any more.try another program like cpuz or occt.occt is an overclocking/monitoring program and may be more than you need but just for comparisons sake.

aldan :

Right, I forgot to mention that I did BECAUSE I heard that SpeedFan wasn't always so reliable.. Here's a reading from CPUID HW Monitor:

There's that reading.

This may be a completely rookie mistake, but I'm just REALLY confused why all of the other temperatures are in there 20s,30s, and 40s like normal. But those 2 just want to act up

71C on the die while idle? The chip is just running hot. Your CPU VCORE voltage is moving or appears the regulator might be failing? It shows a Max reading of 1.424V while current reading is 1.048V. I didn't think the VCORE was supposed to move, at least not that much.

Jay Hamilton · Mar 14, 2014

skit75 :

Ahh ok gotcha so are you saying that something is wrong with the motherboard or maybe a setting in my bios needs to be changed?

Outlander_04 · Mar 14, 2014

VCORE is supposed to move lots . The mb lowers the voltage as processor frequency drops as a power saving measure . That is not the issue .

What thermal paste are you using and how much ? LESS is better . You are trying to fill minor imperfections not apply a layer .

The other thing I would check at this point is how flat and straight the base of the cooler is , and that the plastic mounts on the motherboard are in good condition

Outlander_04 · Mar 14, 2014

You could also check the BIOS to see where the upper temp limit for the cpu is set . The fans might no be kicking in early enough if the target temps are set too high

skit75 · Mar 14, 2014

What I would guess is that you just might be too close to Max power draw from your PSU. Your CPU requires more current which it is not receiving from the supply so when the current drops, the CPU asks for more voltage putting your motherboard CPU Vcore regulator at risk.

skit75 · Mar 14, 2014

Humor me for a minute and tell us your power supply model number.

Jay Hamilton · Mar 14, 2014

Well the thermal paste I'm using is the Antec Formula 7 Nano Diamond. I've used it before and have gotten decent results.

And @Skit75, okay, yea, that's what I was thinking although I've never actually run into the issue. And sure, let me take a look at it really quick.

Jay Hamilton · Mar 14, 2014

Also, I saw this page. What are your thoughts on it?

http://www.tomshardware.com/forum/347455-28-power-supply-causing-overheating

And also, I'm about to reapply the thermal paste one more time, maybe I made it too thick or something. Then next, I'll look into a PSU

Jay Hamilton · Mar 14, 2014

skit75 :

The Power Supply is a CoolMax I-400.

skit75 · Mar 14, 2014

Update us with your new paste numbers.

Outlander_04 :

I could see starving the VCore for power saving purposes but increasing to 1.424V is in the overclocking realm. I haven't owned an AMD CPU in a few years but I suspect that is not a normal, non-overclocking characteristic.

Jay Hamilton · Mar 14, 2014

skit75 :

Alright, reapplied with less past this time and the temperatures are roughly the same

.

On to best buy to go on and get another power supply.
Probably going to go for this one: http://www.bestbuy.com/site/600b-600w-active-pfc-power-supply/2427003.p?id=1219072713094&skuId=2427003&st=categoryid$abcat0507009&cp=1&lp=4#tab=reviews

Because I have no idea what else the problem could be

ah ok gotcha. so is that what's leading you to think that it's the power supply that's the issue?

skit75 · Mar 14, 2014

Well, in an overclocking motherboard you can usually set a maximum threshold.

I would think that even if you were not overclocking, which you say you are not, the threshold for the VCore voltage would be lower by default than what you are reaching in boot-up/idle. Maybe you might reach 1.25 in a "turbo-mode" for example. Above 1.4V seems like it should be reserved for manual tinkering/overclocking. Can someone with an AMD CPU chime in with some advice?

Speed fan showed your +12V rail at over +13 volts also. Generally speaking you should have a +/-10% tolerance on this rail so in theory, 13.2V should be fine. It could be the inaccuracy of Speedfan but, maybe this is indicating something else on the supply side.

Jay Hamilton · Mar 14, 2014

Ok so I went out and bought that power supply and am about to install it. Even if it doesn't fix this problem, by the reviews I saw of my current power supply, I needed a new one soon anyway.

Alright, so what settings would I look for in my bios to change that would bring the vcore voltage back down to normal? I've already tried the fail safe defaults and the optimized defaults.

Would I have to change something on the physical motherboard. This is my motherboard by the way. MSI NF750-G55

skit75 · Mar 14, 2014

Just install the supply and power up to see if anything changes before you start making BIOS adjustments. There is a possibility the motherboard's regulator is at fault and the new supply won't change anything.

I will add that you must be very efficient at navigating BB lines, heh. That was quick.

Jay Hamilton · Mar 14, 2014

lol you could say that. But in actuality, I'm just very determined and equally impatient lol. I need to work on that. So if the motherboard's regulator is at fault does that just mean that it's showing incorrect readings?

Also, would the regulator be fixable (by myself lol).

Jay Hamilton · Mar 14, 2014

Ok, so... I was just taking a gander at the motherboard and noticed that.... the "Easy OC Switch" (which consists of 2 switches) were set to on...

Now the question is... should I keep the power supply now because I feel like that could most definitely have been the issue... Computers make me feel so stupid sometimes...

Jay Hamilton · Mar 14, 2014

Ok so here's an update. Turned off the overclocking on the motherboard and now my Core temp is down to 22C (YAY). But the Temp3 in SpeedFan is still rediculously high. And in CPUID HWMonitor, it shows the same, really high, reading, but is labeled "TMPIN2". But ummm, please tell me that that is just a misreading and my computer may not even have that sensor or something?

Because now all my readings are in The mid-20s EXCEPT for Temp3/TMPIN2

skit75 · Mar 14, 2014

Jay Hamilton :

It is hard to say where the software is doing the math to determine its final value.

The regulator is in theory, able to be replaced, sourcing a solder repair technician with proper tools to reliably replace it is one problem. Identifying and sourcing the actual part is another problem. Unless you know someone who does this on a regular basis, it would be more efficient to just buy a new motherboard.

skit75 · Mar 14, 2014

What is your +12.0V reading now?

It is either a false positive reading or you really do have a regulator on your motherboard drawing too much current. Does MSI have a utlility for measuring thermals? What is it reporting?

Jay Hamilton · Mar 14, 2014

The +12V is reading 12.320V
I'm not sure if it has a utility but I'll check
