Summary0001799: Speedfan hangs on startup, doesn't do anything
DescriptionSpeedfan doesn't seem to do anything.

I haven't been able to figure out whether or not Speefan is *supposed* to be compatible with this motherboard, but either way it doesn't seem to be.

This is a Supermicro H8SGL-F with an Opteron 6128, running under Windows 7 SP1 (64 bit version).

BTW, the 4.44 Beta doesn't work either, it hangs in exactly the same way.
Steps To Reproduce1. Log in with administrator privileges
2. Click on installspeedfan433.exe, follow instructions
3. Click on speedfan icon on desktop.
Additional InformationI have attached a screenshot depicting this particular flavor of "hanging on startup".
TagsNo tags attached.

Try this: copy ONLY speedfan.exe to another (even temporary) directory and run it. Does it still hang?

Thanks for looking into this. Yes, it still hangs when running it after copying to an otherwise empty directory. I noticed there was a file named "debug.nfo" created on that occasion. I attached this file in case it's helpful.

debug.nfo is interesting. Do you always get a debug.nfo like that when your start SpeedFan?

Yes, this seems to be the case.

Thank you. I will look at the source code to see what causes this issue.
By the way: do you experience the same issue with SpeedFan 4.42?

Thank *you*. No, I have not tried that, because I'm a first time user. I tried to find the previous version SpeedFan 4.42 on your site ( and elsewhere, but I did not succeed.

Thanks for mailing the program. We're getting somewhere, 4.42 runs on my box, albeit not perfectly: This is what it says on startup:

Maybe these entries give some clue.

Oops. While I wrote this, the H8SGL box's screen went black. It just spontaneously died on me, and it doesn't respond to the power button either.

Didn't respond to the power button. I had to unplug it from the mains, wait half a minute, then plug it in again. It's still functional. Phew.

I experience the same "issue" on one computer, too.
In my case, it looks like the check of the certificate is taking a long time.
Did Speedfan really stop responding? In my case, it looks like it ran into a timeout when checking the (*.exe-)Certificate; after about 35-40 sec's of doing "nothing", Speedfan continues normally.
Debug is like (look at the time):
07.04.2011 00:41:06.586 - FORMCREATE : found ASUSTeK Computer INC. P7P55D Rev 1.xx
07.04.2011 00:41:06.586 - FORMCREATE : before PostMessage

07.04.2011 00:41:41.379 - SpeedFan executable is properly signed
THIS is for sure a problem of my computer, but I'm not sure which, at the moment...

What you think is the issue is exactly what I expected it to be. The large delay you are experiencing is clearly shown in DEBUG.NFO file. I need to find out what could be causing this delay.

Is there a way to prevent the certificate check, if only to test that hypothesis?

edit: by way of clarification, the computer in question is not connected to the internet, and is not meant to be.

Therefore it's logical that SpeedFan doesn't run, if it requires an internet connection to check certificates or something.

I tried it the other way, and plugged the computer in. Speedfan 4.43 started, showed some nonsensical readings, and then the screen went black again, the computer dead again. Same procedure as yesterday.

It sure looks like SpeedFan is seriously fucking with my hardware. Sorry guys, I'm out.

no Internet Connection needed (except SpeedFan is morsing home, haha!).
The Certificate Check is done on your Computer. Usually, all necessary Certificates
are installed.
I have solved the problem here. It was an outdated Certificate from
"Class 3 Public Primary Certification Authority" (valid until 08.01.2004).
Deleted it(!) and installed the current one valid until 02.08.2028 (is in the speedfan.exe-Certificate).
Tricky; usually no need to clean up Certificates, but it helped here (4.44b4)!
