Hello everyone... I have a Zotac 5070ti sff... my problem: when i mount it in my Thermaltake The Tower 600 (i.e. hanging 90 degrees), the card gets loud and extremely hot... as soon as i mount it horizontally 180 degrees again, everything is ok... is this a defect or is it normal?
As I understand it, the card is not defective as soon as the card is horizontal, you write that everything is fine. If it is defective, it would be exactly the same with the horizontal one. I would have a look at the air flow. Does enough cool air reach the graphics card when it is 90 degrees vertical?
What is "loud"? The RTX 5070Ti, when installed "horizontally", switches off its fans in desktop mode and cools itself passively. I would find it plausible that this works better "horizontally" than "vertically", because the resulting air circulation "horizontally" can provide more cooling due to the greater width of the "chimney".
With the card, the warm air (when PCIe is "down") is distributed upwards when the fans are running, to both sides (slot bracket and opposite) and "backwards" in the case of the third fan. The two temperature sensors are probably located in the GPU and its memory, i.e. on the board, in the half adjacent to the slot bracket. According to HWMonitor, the card sometimes reaches 300W in the long term. It is then important that the air drawn in by the fans is as cool as possible. It would help if the warm air could be removed easily. The possibilities of the fans end somewhere around 2500 rpm.
I only know the TT TT600 from pictures. The airflow is good in my case. There is no other card and the RTX fans sit close to the case opening, so the air drawn in is at room temperature. Relatively close behind the card, other fans then take over the further transport. However, after the first attempts at using these fans, I set the temperature control by the mainboard in the BIOS to be more sensitive than it was by default and extended the temperature monitoring to several available sensors (CPU, memory, another measuring point). This means that they run a little faster even at lower temperatures and accelerate earlier and faster. This allows me to get the system's power loss of up to > 450W under control.
You can tell whether a cooling system is working well if the system cools down quickly as soon as the load ends. The RTX 5070Ti oscillates between 20W and 300W, the processor between 20W and 150W. Both heat up very quickly, which the ventilation has to support. Even if the RTX50 is more energy efficient than the RTX40, physics is still physics.
