Quick Answer
For Deepcool LT720 in Corsair 5000D, plan the GPU fit around the radiator-and-fan stack first, not only the case headline clearance. Use 52-55mm as the practical AIO stack allowance, then compare it with the graphics card length and power-cable bend. Most RTX 4070 Super and RTX 4080 Super class cards fit comfortably in roomy mid-towers, while oversized RTX 4090 cards need a measured check before ordering.
Clearance Math
| Item | Planning number | Why it matters |
|---|---|---|
| Deepcool LT720 radiator plus fans | 52-55mm | reduces front or side clearance when mounted near the GPU path |
| GeForce RTX 4070 Super 267-300mm class | 267-300mm | usually comfortable in mainstream cases |
| GeForce RTX 4080 Super 310-340mm class | 310-340mm | check front radiator and cable bend |
| GeForce RTX 4090 304-358mm class | 304-358mm | verify exact model length and slot width |
Where The Fit Can Fail
The card can clear the radiator but still fail at the side-panel cable bend, vertical mount bracket or lower fan position. A 12VHPWR or 12V-2x6 cable needs a gentle route, not a hard fold against glass. SA builders should check the exact Evetech listing photos, model length, slot width and warranty path before mixing a premium case, AIO and GPU.
Local Build Notes
Budget roughly R2,200-R4,800 for a 360mm AIO and R14,000-R35,000+ for the GPU tier, depending on whether the build targets 1440p or 4K. A Ryzen 7 7800X3D with an RTX 5070 Ti or RTX 5080 class GPU is a common high-end gaming pairing. Keep at least 10-15mm spare space where possible so future upgrades do not require rebuilding the cooling layout.
FAQ
Will an RTX 4080 Super class card fit?
Usually yes in roomy cases, but check the exact card length and the radiator mount position. A front or side radiator can remove 52-55mm of usable space.
Is top mounting safer for GPU clearance?
Top mounting is usually safer for GPU length because it keeps the radiator away from the front card path. It can still clash with tall motherboard heatsinks or thick DDR5 memory.
What should I measure before buying?
Measure GPU length, slot width, radiator stack depth and the cable bend near the side panel. Those four numbers decide the fit more reliably than a general case family name.
Clearance tip
Add the AIO stack depth to the GPU length check and leave 10mm spare for cable bends before finalising the parts list.
