HEATKILLER V PRO graphics card coolers for Nvidia's RTX 4090 Founders Edition have been specially developed to cope with the high power loss of 450 watts and more.In order to ensure a correspondingly high increase in performance, we decided on a modular high-performance base plate.Proven technologies such as the dual-layer inflow and the symmetrical cooling design have also found their way.The result, in the form of the HEATKILLER V PRO series, is impressive both visually and in terms of performance.Important key points of the HK V PRO series:High performance base plateSelected high-performance thermal pads on the GDDR6X RAMDual layer inflowSymmetrical cooling designDesign-integrated connection threads in the terminalScrewless designInsulating spacers made of high-performance plastic (peek)CNC cut thermal padsModular high-performance base plateIn order to increase the cooling performance in the GPU core area, we have integrated a modular high-performance base plate into the heat sink.With finely slotted fins and the associated increase in the cooling surface, this ensures a significantly higher cooling capacity than a monolithic design is capable of.We chose the fin structure in such a way that, in addition to increasing the performance of the GPU core, the flow rate is also kept high.All distances to heat-relevant components were kept tight, which means that the heat from thermal problem areas such as GDDR6X RAM and voltage converters is ideally dissipated.The PEEK spacers made of high-performance plastic ideally insulate the cooler from the circuit board and facilitate assembly.The legendary Kryonaut thermal paste from Thermal Grizzly ensures the best possible heat transfer.Dual layer inflow and symmetrical cooling designThe dual-layer inflow can be found, like the symmetrical cooling design, in the PRO version of our HEATKILLER V GPU cooler.The increased inflow is particularly important for the high-performance base plate.The splitting of the water on two levels
