You could likely buy another brand that is the same exact cooler for the same price or less as the used Dell cooler will cost. The thing about the Dell CPU cooler, is that as far as I can tell, it's not designed by Dell and is just rebranded for them. So the model for that CPU cooler would be 89R8J X3JDD. 89R8J G8CNY is the 95watt TDP CPU cooler. CPU cooler is the fan and heat-sink together. Typically you would be running a 90mm-120mm tower cooler that is rated at around 125-200watt TDP for an i7, but it's not always necessary to have the best cooler if the case has good ventilation.Ĭlick to expand.89R8J is the model of the fan itself and G8CNY is the 95watt TDP heat-sink. You want a CPU cooler that is rated for at least the CPU TDP, to keep the CPU from overheating past its thermal throttle limit. The CPU should be using less power than the CPU TDP under load. That wattage is not how much the CPU uses, but the TDP or thermal design power. When I made the 4770S my main system, I replaced the cooler with a Coolermaster Hyper 212 Evo 120mm tower cooler and dropped temps to 60-65c under load. I have no idea what the rated TDP is of that cooler, but I'd guess about 65watt. I should mention though that the stock Intel cooler that came with my 4770S was barely enough to keep it under 80c when I was running it as a server before using it as my main system. You likely won't need a PSU upgrade to run the non-K model CPUs, but I would still look for an i5/i7 S model 4570/90, 4670/90, 4770/90 if you don't want to replace the cooler for whatever reason. There is a decently cheap ($10-20/ £7.50-15) 95watt TDP cooler (0G8CNY) that Dell installed on the higher TDP CPUs in the SFF case, so you have at least that option. The lower end cooler is rated for 65watt TDP CPUs. The S model would be the best and faster CPU option without having to worry about replacing the PSU and the CPU cooler. That is partly why I was suggesting you buy the S or T models. I really don't know what cooler will fit and can't find any definitive answers as of writing this. You might also have the possibility that Dell did not use standard Intel cooler mounting holes on the motherboard so you might not be able to use other coolers easily. The issue you have with an SFF case, is you are limited to a small selection of slim coolers. Typically you would be running a 90mm-120mm tower cooler that is rated at around 125-200watt TDP for an i7, but it's not always necessary to have the best cooler if the case has good ventilation.
