Video Card Problems/Possible Heat fix
I am looking to change up this build if needed. I am also looking into OC both CPU and GPU. I already know the GPU runs pretty hot, so if someone would kindly help into finding a fix for that it'll be great. I wanted to get a CPU cooler and I do know about cooler brackets for GPU. Is there a way to possibly set one CPU cooler to both CPU and GPU?
CPU: Intel Core i5-4690K 3.5GHz Quad-Core Processor
Motherboard: Asus Z97-A ATX LGA1150 Motherboard
Memory: G.Skill Ripjaws X Series 8GB (2 x 4GB) DDR3-1600 Memory
Storage: Samsung 850 EVO-Series 120GB 2.5" Solid State Drive
Video Card: XFX Radeon R9 290X 4GB Double Dissipation Video Card
Power Supply: Corsair CX 600W 80+ Bronze Certified Semi-Modular ATX Power Supply
I would suggest a competent heatsink for the CPU - there are many options at many price points. Arctic, Thermalright, Thermaltake, Cooler Master, and so forth are all popular choices.
For the graphics card - the Double Dissipation cooler for the 290X performs very well as-is, it is unlikely you will need to replace it, and it is also unadvisable as it will invalidate the warranty on the card. As far as a "combined" solution, you cannot do this with air cooling, however a water cooling system would be capable of that (you would, however, still void the warranty on the XFX card upon removing its heatsink). There are other options for a liquid cooled card, however, such as the HIS IceQ Hybrid, which uses a hybrid air/water cooling system, and comes with one of the highest factory overclocks of any 290X.
