NH-D9 TR5-SP6 4U,NH-U14S TR5-SP6
The NH-U14S TR5-SP6 on average was around three degrees cooler than the NH-D9 TR5-SP6 4U or about seven degrees cooler for the peak temperature. The difference is understandable given the NH-D9 being more compact to fit within 4U height requirements. The slightly better performance with the NH-U14S TR5-SP6 is even with this Noctua cooler for most TR5 socket orientations (including as tested) blowing the CPU hot air up towards the power supply rather than in a straight front-to-back orientation as with the NH-D9 and other common heatsinks. With both of these Noctua coolers costing similarly, it ultimately comes down to which heatsink will fit better within your chassis.
"Long story short, the Noctua NH-U14S TR5-SP6 and NH-D9 TR5-SP6 are great heatsink fans for keeping the Threadripper 7000 series cool." (Michael Larabel, Phoronix.com)
