The cooler in QHY367C can lower the CMOS temperature to a value that’s almost 40 degrees
centigrade below the ambient temperature. So you need to be careful to avoid thermal shock,
which refers to when the cooler’s temperature rises or fall dramatically, the cooler is
subjected to strong internal stress due to contraction principle. Drastic thermal shock can
shorten cooler’s service life or permanently break it.
So when you begin to adjust the CMOS temperature, you should avoid setting “Cooler Power”
to its maximum value, and you should gradually turn up the “Cooler Power” value. When you
turn off the power, if the “Cooler Power” value is very big, you should gradually turn it down
before turn off the power.

The FPS of cameras sometimes suddenly drops to zero under DDR mode on
SharpCap, what’s the solution for this problem?
Recently, we have been told by our users that the FPS of their cameras sometimes suddenly
drops to zero under DDR mode on SharpCap. It is caused by the fact that the receiving speed
of computer is relatively slower than the sending speed of camera. Once CMOS sensor starts
working, it will incessantly conduct exposure and output image data over and over again, and
it cannot be interrupted. If USB transmission was interrupted too often by the operating
system, the data overflow of DDR would ensue resulting in bad frame. Therefore, not a single
frame is a complete frame, and the FPS will drop to zero.
Solutions:
The first solution to this problem is to increase the value of USB traffic to decrease the FPS of
the cameras. Note that by using previous version of SharpCap Patch, the value of USB traffic
cannot be set to a value large enough, so you should go to our website to download the latest
version of SharpCap Patch.
The second solution to this problem is to turn off the DDR mode, but for computers whose
performance isn’t very good, this solution may not work very well.
