Engineering Support

Imagine your high-powered CPU overheating in the middle of a crucial task. That sudden shutdown not only frustrates you but could spell disaster for sensitive electronics in cars or medical devices. Cooling Source offers engineering support services that go way beyond picking a part—they help you build systems that stay cool under pressure, preventing failures and extending device life.

Quality Control

Quality control sits at the heart of Cooling Source. It’s not just a check at the end. Top makers treat it as a must-have skill to land big supplier deals.

That is amazing news! Thank you for all of your help!   Yes, it looks like I will only need the original 10 to go air, and the rest can go by boat to deliver as we have scheduled (50 pcs 1/22/16 and 60 the unscheduled balance of the order.   I hope you all have a great weekend!    Thank you,

Hi Ben, We showed our proposal to the customer early this week, they are happy with the heat pipe and cold-plate cooling solution, but need to re-evaluate the system electrical structure, as well as our part. Since the cooling design will be changing with the electrical design, we need to wait until the customer’s evaluation is done.  We put this project on hold now. Thanks so much for your deep involvement in the challenging integration design and provide excellent details on the manufacture requirement of the heat pipe! We also highly appreciate your quick response!  Thanks a lot! Let’s keep in touch. Regards,

Xintong

The simulations helped us to make the decisions on a project. Going forward, we will contact you looking for a heatsink suited for some of the new devices we are trying to promote. Due to the large size, it may require something larger than what Is available on standard heatsinks. Thank you again for your fast response.
