Fan Control question!

[fts3v3r]

I was looking at my Fan Control settings and I noticed it said my Right fan was running at -1 RPM. Is this normal??

What computer do you have?

Also, do you have a link to that wallpaper? That is nice!

Perhaps it's not reporting speed correctly. Perhaps your fan is running at max? -1 could be max speed? It's a common programming shortcut.

I know with the uMB, the -1 was because there was only one fan. Are you running the base 15-inch MacBook Pro with just the 9400M? If so, that might be why, you only have one fan? I haven't seen a teardown of the mid-2009 MacBook Pro so I can't say for sure that the base 15-inch has one fan instead of two.

Someone was having the same issue on another forum and it turned out that his MBP had only one fan. Here is the quote:

Just for future reference guys, the uMBP 15 with the 9400 only just has one single fan. I had all this information pulled up during my argument with the Genius, so he finally took the back off and showed me. lol....

If you have the same model, then the reading is just indicating the absence of the second fan. If you have a different model with two fans, one of your fans is not working.

Here is the site where that wallpaper came from. I have the same picture on my MBP

I have the 2.53 13in MBP.... not sure if it has one or two fans?

I believe that specific model has only one fan, meaning this is perfectly normal.

You have only one fan. There, your problem is solved. Fan control is assigning -1 to a piece of hardware that doesn't exist

Sweet, thanks tenderidol!
