What's the system reporting for ambient temperature? Any chance something came unplugged/hooked in the move?

It's likely that the CPU either tripped over the final "step" in its fan ramp, or the ambient temperature is higher inside the system, and that's what prompted the fan to spin up. But because it's not likely substantially hotter in that room, you see somewhat lower temperatures as a result.

All temps except CPU idle about 4 c higher than they once did. That's also about how much hotter it feels up here with the computer going than where I previously was.

Just played some Morrowind... highest the CPU supposedly got was 46 c yet the CPU fan speed hit 4200 RPM, a full 500 RPM higher than what I would normally hit at 60 c. o_o;

I guess it's possible something got tripped up in the move, though I can't imagine what. I had the computer in the back seat of Dad's truck and we only had to drive about 10 minutes to our destination. So far, aside from the odd CPU fan speed, the thing's working as expected. :B

I would check that the HSF is still seated right - I've seen those get bumped even without the machine traveling by car, and it can affect temps. It sounds like whatever is controlling the fan may be taking ambient temperature into account as well, and the higher fan speeds are resulting in lower running temperatures because the increased ambient temperature isn't dramatically higher. Of course, this *is* an AMD FX, so the explanation that aliens are sending z-waves into it to plot an invasion is likely just as plausible. 🤣 😲

If you want your CPU to run cooler, try:
- cleaning your fans
- cleaning off your current CPU thermal compound and applying fresh compound
- lowering your CPU vcore
- reconfiguring your case fans
- or, if all else fails, underclock

I'm not sure if this actually helps, but I often run my desktop with the side panels off. Theoretically, this should allow for more ventilation, but I've also heard that it can interfere with certain cooling setups. Try it and see if your temps drop, unless you have fans installed on those panels.

Well, for the moment, the temps are not concerning, but it's odd that the CPU fan speed is so much higher overall for the same temps following the move.

Also, I seriously doubt the heatsink has shifted. It took an incredible amount of force to lock it in place at all. The only way it could've possibly shifted is if something around the assembly cracked or broke. I'll take a look this weekend (or sooner if I run into major issues).

It depends on the case's airflow design. Positive pressure or channeled airflow designs will benefit from having side-panels on, but "conventional" configurations that just rely on a normal intake/exhaust scheme will probably benefit from the side panels being off.

I have a fairly normal push/pull setup, so that probably explains why it works fine for me.

My advice would be to acquaint yourself with the SpeedFan software... There's a bit of a learning curve to it. I had to use it on a Vostro 420 where Dell skimped on the BIOS and there's only a very rudimentary AMI BIOS which doesn't control case and CPU fan speeds at all. It's very flexible and powerful software, and you can tweak your own fan/temperature curve with it. I've also seen this sort of control available in newer MSI BIOS, so you might want to check your BIOS out too.

Can you post your system specifications?

Good luck on it. Of all the machines I have ever had, I have only found ONE
where speedfan could control the case or CPU fan

Have you measured the voltage on the wall socket? Might be the voltage is down, less voltage means more current and more current means more heat.

Like I said, you have to learn how to use it. It's not just a simple as running the software. Each platform requires its own set of tweaking depending on what type of monitoring/pwm chip is being used. Out of the box so-to-speak it didn't work, but as soon as I configured it, it did exactly what I wanted it to do, ramping up both the case and CPU fan automatically depending on the temperature.

My only gripe with the software is that you have to set it up in a roundabout way in order to get it to run automatically when Windows starts. I wish it would run as a system service, but the author has not implemented this yet unfortunately.

You can launch software through the Startup folder or the Task Scheduler. It's not that hard. 😀

My CPU fan spins slowly. The cooler is a huge mofo. I recomend buying something like that. 😊

Last night when processing gameplay footage for editing today the CPU fan got up to 5300 RPM, 1100 RPM higher than I've ever seen it and 1600 RPM higher than typical for doing this sort of activity... yet the CPU temp was the same as always, topping out at 56 c for about 65% CPU usage. ALL other temps however were about 4 c higher than usual, which is about how much warmer it is where my computer is now compared to where it previously was. Once the CPU cooled back down to 40 c where it tends to idle at, it was still running the CPU fan 600 RPM higher than when I started.

During the process I felt the air coming out of the top case fan which is mounted right above where the CPU is and it didn't really feel any hotter than usual for this sort of thing. *shrugs*

It's possible some other reading is contributing to the fan speed increase, or perhaps ALL of the readings were being factored in, but the temps are clearly being reported correctly so I'm not too concerned. So long as the CPU stays under 65 c there's nothing to worry about and every other reading from the numerous sensors on the motherboard topped out between 37 c and 47 c, not counting the sensor placed right under the CPU, which always measures slightly hotter than the CPU itself for whatever reason.

My monitoring software has the ability to graph all temperature sensors over a period of time. I'll set that going before I do my final render tonight and see if that reveals anything interesting. :B

As for fan control software, I don't have any installed because the last time I did I ran into issues with the case fans not being run properly, so I just let the BIOS take care of it now.

Do the fans sound 5300 RPM? 5300 RPM is *very* fast

It sounds like your temps are okay. 47C is perfectly safe. Maybe the speed profile got changed somehow?

Yes. Sounds like a jet engine and fairly high pitched.

I doubt that considering I had it set to "100%" in the BIOS beforehand. I can't adjust the RPM directly, only the percentage of maximum speed. :P

Does your bios have different fan speed profiles, optimized for quietness, performance, etc? I have an older ASUS board with the Q Fan feature, and enabling the "Silent" profile makes my system nice and quiet, without adversely affecting temps. I also manually set my vcore, because my board sets it obscenely high when I leave it on auto, and I don't even need it to be set high for stability.

OK, I'm fairly certain now that some kind of sensor somewhere in the system which I can't measure is contributing to determining the CPU fan speed.

See, my system's actually fairly close to the heating vent for the room... there wasn't any way around that. When the heat comes on, if the system's idle, the CPU fan speed slowly rises by about 500 RPM, then when the heat goes off it slowly drops back down... yet the most the idle temps increase by is 2 c during this. 2 c normally only covers about 200 RPM, not 500 RPM.

Also, I was able to get the system up to about 95% CPU usage peak during rendering of my latest ADG episode last night. I know from past experience that running the CPU at full power typically brings it up to 62 c. However, the highest the CPU temp got this time around was 60 c, and it only peaked there as it mostly sat around 59 c. Granted, the CPU fan was going like a bat out of Hell, topping out at 5500 RPM and mostly sitting around 5300 RPM during the rendering.

So, even though the CPU fan is running faster due to the warmer environment in here and the proximity to the heat vent for the house, the CPU temp itself is ending up slightly cooler as a result of the generally higher fan speeds. *shrugs*

Yea I ended up using the task scheduler method. The startup folder method was no good, because it needs to be run as an administrative task. There's a bug though with the task scheduler moethod, when you do it that way, it will not read GPU temperature properly. I'd like to control my Radeon 7770 with it too, because the default settings are a bit lax.

Another caveat is that you can't have multiple users logging on and off with it running this way. It will mess up, because it doesn't close at each logoff or something like that. He really needs to program it to be run as a service.

Ironically, the only fan that speedfan can control on my system
is the one in my radeon GPU. The GPU temp works for me
but I use MSI afterburner because it is more flexible for fan control.
