I got tired endless reviews and of wondering If a new cooler would make any difference in the cooling inside my case and so after a trek to Micro center I decided to purchase a Megahalem cooler to compare it to my current Noctua. My Noctua is one hell of a cooler but was being overwhelmed buy my case temps and every review I read said it was on par with the Meg, TRUE, Hammer and all the rest. Orginally I was going to purchase a TRUE RT 1366 revision B with the new fin arrangement but look at my feet to see the Megahalem on sale for 10.00 less. So here is the comparison Noctua NH-U12P with a Antec TRI cool 120mm fan 78CF in push pull with a Noctua 120mm 55CF fan verses a Megahalem with a single Antec Tri cool 120 mm 78CF couldn't added a second fan because a second set of clips are not sent with the MEG. So The Noctua has the benefit of a 55 cf additional fan. Both heatsinks had Noctua NT-H1 thermal paste applied but again the Noctua had about 3 months of curing as a advantage so here we go. Testing was done in my Thermaltake armor case with a solid side panel on. Room temperature is 70F, my case has 5 120mm fans, two 92 mm fans and a 140mm psu fan. The Noctua once again get an advantage because the Meg loses a 120mm fan from the heat sink. Here is the test.. 1.Noctua NH-U12P with a Antec TRI cool 120mm fan 78CF in push pull with a Noctua 120mm 55CF fan 2.Megahalem with a single Antec Tri cool 120 mm 78CF My mouth dropped when I saw this and this is with one fan and remember the Noctua is no slouch of a cooler. Okay Found a rubber band to rig up a second fan on the Meg and a 4c drop in max temps occurred Halloween art work is by my 10 year old daughter feel free to copy and paste it LOL!!!
