FYI he using xp120+vantec 120mm bling bling fan
then are your casing very pack? the cable are well organized? if the cable hanging around like spider web in front the HFS, then there is no way the hot air go out. if everything seems fine, maybe reapply thermal paste like AS5 may help bring down temp a bit. Ever think of screw a fan on the alu net to draw cool air above CPU?   Well, just my 2cents. 

Check your mounting.. If mounting not good, it will affect the contact between the cooler and your processor IHS. Thus, increase the temp.

If you really change to 3.0E, a third party cooler is HIGHLY recommended. It is one of those 'very hot' processor. Or you can try to look for those 3.0C. Much cooler.

Err... Dream X3 is a very so so heatsink. It is quite impossible to cool down your 3.0E

if possible just direct screw the fan on the alu net(promised that wont spoil the net), blow air on your HFS. 

my friend tried to put 4 fans on his panel like yours, 2 intake 2 exhaust. Not so loud if you using silent fan. i still remember his 7000rpm delta fan playing hard rock concert on the alpha cooler

currently i open my side panel and a stand fan blow directly to it. lucky dont have cicak lipas. My prob now is the dust.
hoho...nice to hear that. fast fast pasang and rock your cpu.
