Same starting temps, the case fan at roughly the same RPM, heatsink fan 1166 RPM. The computer's thermal profile allows things to heat up to a point, then runs fans faster to maintain that temp. Test results were- CPU, max 74 deg (and climbing max 2324 RPM, case RPM. First, the stock heatsink- At rest, CPU temp 41 deg 959 RPM, case RPM.

Same stock processor, a premium thermal paste used in each case. Measured fan speed and temperatures using the HWiNFO64 utility. 10 minutes of the CPU Stress Test, immediately followed by 10 minutes of the Memory Stress Test.

I tested using Intel's Extreme Tuning Utility. The J9G15 redlines at 5667 RPM, and curiously, the same case fan runs slightly slower at 3010. With the RD6XX, CPU fan maxes out at 4700 RPM, the case fan, 3200 RPM.

First, I switched off the automatic fan control in BIOS to record CPU and case fans at full speed in ePSA (Warning- this will cause ePSA Diagnostics to hang up on the processor fan test). The difference? The J9G15 (left) has a copper core and a more powerful fan.

So I buy, and install (gee, I'm doing my own service call ).ĭimensions, connector, and shrouding are identical. Multiple vendors on E-Bay and Amazon are offering this, p/n J9G15, new and used, for prices not much different than the RD6XX. Do my research, and the case and MDB configuration is pretty much identical. Learned that is the next generation of Optiplex after the 3020/7020/9020, supporting 5th & 6th Generation Intel processors. Then one day I see an E-Bay listing for a "high heat" fan/heatsink for an Optiplex XE2. Made note that my RD6XX fan/heatsink was the best available for this SFF case. In my web surfing, I noticed that Intel provides a different fan/heatsink for the "K", with copper core instead of straight aluminum. It currently has the i5-4590 CPU, made note that faster i7-4790 & i7-4790K processors will work, though there is concern that the hot-running "K" CPU will overwhelm the cooler. Proprietary cases, MBDs, fan connectors are nothing new to me in the Dell world, but the challenge of "hot-rodding" this tightly packaged SFF has provided some fun

I carried an Optiplex 745 absolutely as long as I could (that heady mix of "because I had to/because I can"), retired it recently and got a refurbished ex-office 3020 SFF. A service provider with a Dell account got me into the business, and I have trusted Dell enough that my home computer has always been a Optiplex of some sort. I am recently retired after a 20 year career doing warranty repair work in computers, printers, flat screen TV's, and other things.
