Beyond Posted January 15 Report Share Posted January 15 On 7/25/2022 at 6:45 PM, Clouds said: Hi folks, I've had the V71 since it came out and for quite some years now have been wondering if it's possible to replace the front I/O with more up-to-date tech, instead of the old USB 3.0 and 2.0 ports, but keeping the mic and headphone ports? Thanks in advance! Hey Clouds, I was wondering what you ended up doing in terms of trying to update the case? I went over all of ThermalTake's current cases and even looked at a view videos listed as "The top cases of 2023" as well as going over all the advertised cases for CES 2024. Perhaps it's so hard to find a similar case to the V71 because people nowadays use DAS/NAS systems attached to their set-up and would avoid having all that extra room taken up by the HDD bays.

Bendr80 Posted January 17 Report Share Posted January 17 Good afternoon, the microcircuit on the controller board burned out. How can I find out the markings? I can fix it myself and it’s not difficult for me. marking on the GoFaF chip. What kind of microcircuit is this? Or maybe there is a diagram of this controller board (qb-1308-1 fan).

My controller board is slightly different, but I think the chip is the same. This is WS5203 monolithic synchronous buck regulator. Quote Link to comment Share on other sites More sharing options...
raritetvidali Posted May 18 Report Share Posted May 18 I will also tell you about the difficulties I encountered and how I solved them. As mentioned above, some hard drives do not fit the case mounts. I have this enterprise class drive HGST Ultrastar HUH721008ALE604. I simply cut off one of the tabs on the mount. The fan at the bottom of the case is easily attached to the holes in the grill using flat screws. But I used rubber fasteners. I inserted the rubber bands so that the bottom of the case fit into the bottom slot. In this case, the fan is slightly raised. However, at high speeds the dust filter began to rattle. To fix this, I bought a soft window seal 1 mm thick (it looks exactly the same as the one glued to the bottom of the feet, only thicker) and pasted it over the dust filter around the edges. To ensure that the feet do not interfere with installation, they can be removed by carefully peeling off the seal under which the screws are hidden.

raritetvidali Posted May 18 Report Share Posted May 18 Now I’ll tell you about the fan controller. The case uses non-standard fans with a modified board. In standard fans, the yellow wire is used for the speed sensor. In Core V71 fans, 12 V is supplied via the yellow wire to power the backlight. This is why standard fans cannot be connected to the built-in controller. If you remove the yellow wire from the connector or cut it off, you can connect a standard fan to the controller and the speed switching will work. But you can't control the backlight. The problem is that the markings of the built-in fans are exactly the same as the standard ones. Immediately after purchasing the case, I decided to install a fourth fan on top and bought another TT-2030 on Ebay. However, the fan sent was standard. It has a non-switchable backlight and a speed sensor. The speed of the built-in fans cannot be read, only the backlight glows slightly. It also turned out that in the High mode of the controller, the fans are supplied with a voltage of 9 V, and in the Low mode - 6 V. Even at 6 V, the fans seemed noisy to me, so I made cables with a 10 Ohm resistor to slow down the fans. Now they are silent. Although Thermaltake's website states that the fans start at 9V, there were no startup problems. Beyond 1 Quote Link to comment Share on other sites More sharing options...
raritetvidali Posted July 6 Report Share Posted July 6 Changed the power connector to SATA and removed the wire with the Molex. At the same time, I washed off the remaining flux from the PCB. Beyond 1 Quote Link to comment Share on other sites More sharing options...
