QSI fans speed changing by itself

[andysea]

I am posting this as someone on the QSI group suggested.
I use the latest version of SGP 2.3.15.2568.
For about a year now the settings on my QSI camera always revert to fans on high speed. Typically the fans used to be on high speed when the cooler was at 100% then they would slow down to quiet mode after the camera had reached the set temperature. Now, that no longer happens and the camera fans remain on high speed. In order to revert to quiet mode I have to disconnect the camera from SGP, open the QSI properties, select quiet mode and then reconnect to SGP.

I think it might be a driver related issue and not related to SGP, but I am posting here to see if anyone has encountered the same problem.

This happens with my 583 and with my 532 cameras. QSI has a protection in the firmware that speeds up the fans if the body of the CCD is at 35 degrees or more. That never happened to me, especially these freezing winter nights.

Thanks!

Andy,

I think it was already fixed in 2.4 Beta.

QSI fan speed quirk

A friend and I both have observed the following quirk with the fan speed control on the QSI(683) Irrespective of the fan speed setting, the fan always turns on fully with TEC, even when the temperature is reached. We found a work-around but am not certain if it is the driver, or SGP: -connect the camera -run with the cooler on -disconnect camera but do not turn off the cooler -change the camera fan setting to quiet -reconnect The quiet mode works now... but this process needs to be repeat…

Sequence Generator 2.4 Beta is Released for Testing

Welcome to the SGPro 2.4 Public Beta! We have been through several months of internal testing and we feel like 2.4 is getting pretty close to release. That said... this is beta software and you should have two expectations when you use it: You cannot be too angry if it sets your sequence on fire If things go wrong, you should be willing to report issues, complete with reproduction steps and SGPro logs Betas are not for everyone. If this sounds like something you would like to participate…

Andy,
This has already been addressed in the 2.4 beta. You can now set the fan speed to whatever you like in the QSI settings in SGP.

Ahh thanks!
I will keep an eye out for the official 2.4 release.
Interesting, I thought it was a QSI driver issue.
