Do you think I can get away with the Asrock cooler (lol) for the first few days with the Xeon? I think my Narrow ILM mount from Noctua won't arrive until after Christmas.
Should be fine! I'm running a Xeon on an even weaker cooler, the Dynatron T318 with a fan attached with zip ties. Temps aren't great though... low 80's at full load, idle in the 40's.
