Hi, guys.
Thank for the replies and suggestion.
I've measured the voltage at the heatbed terminals and they're at 12.95V but still not getting to the right temperatures and not staying at a set temperature.
I do have an extruder fan and I will do the suggestion of adding the baffles for the redirection of the airflow.
Also, I have added silicone pads underneath the heatbed with a small airgap in between. It helped, but not so much.
And yes that is my power supply as seen on the picture.
Could a factor be my software? I'm running on Sprinter but almost everyone here I see is using Marlin.
Thanks guys. I really appreciate the help. Almost coming to 4 months of this thing!
