Thank you for taking a look at my problem personally Nando4! Alright I figured out that the PE4H adapter was bad and replaced it, and that fixed the fan problem, and the rest of your input especially the boot order was very helpful in detecting the eGPU. However, things aren't quite working yet. The Problem: Although the card properly is identified and the drivers are up to date the card is unable to run any real computations like OpenCL. What I Have Tried: After the card was detected I reinstalled the AMD Catalyst Suite this allowed the graphics card to be specifically identified. Played around with component power up and boot order. Alternatives I'm Playing With: I obtained a PE4L 2.1b as well to see if that would help, and so far I haven't been able to get that to work either. Problem With Alternative So Far: If I try to power things up in the above order that worked for the PE4H the screen goes to the first white screen and never loads the OS. If I try to change the boot order the system loads but the card is not detected. Thanks again any help you can offer would be appreciated!

Hey! Thanks for stopping by to give me a quick hand The Problem: eGPU fan isn't starting and the system is unable to detect the card. For now lets assume that I can get the card detected if it is properly powered up and the fans are working. System Setup: OS: Windows 7 64 Bit System: Mac Mini - Running on Boot Camp Ram: 16 GB eGPU: AMD Gigabyte Radeon 7970 PSU: 840 Watts, 70A, +12V Cabling Approach: Thunderbolt -> PCI-E Card Reader -> PCI-E HDMI Converter -> PE4H; PSU provides power to the PE4H as well as to the eGPU itself. Current Status: I am currently able to get lights D2, D3, and D4 to green, but D1 is red. I would love to know what that means as it might provide insight into the problem. This occurs when both the PSU is on and when the PCI-E card is plugged in through thunderbolt+adapter. If PSU D4 goes off, if adapter is disconnected and PSU is on I get faint red light on D1 and a green D3. Note: The card does heat up, but the fans don't spin. Query: Could it be a bad PE4H board? Random Question: Should I be worried or checking jumper status, if so what should it look like? What I Have Tried/Done: eGPU drivers installed. Attempted swapping out numerous cables and even the eGPU itself to see if it was a bad card. Restarted OS and tried numerous timing combinations of turning things on and connecting while booting. Looked through FAQs, run google searches... Attached are images of my setup.
