Gigabyte z87x-ud4h quick question about pci express x16 speed

[angelfrost]

Hi dear experts!
my system is this:

cpu:i5 4670k (stock)
cpu fan:coolermaster hyper 212 evo
mobo:gigabyte z87xud4h
ram:16gb corsair vengeance 1600
gpu:gigabyte 660 oc edition
case:coolermaster cm 690II advanced
psu:coolermaster 850 silent pro
ssd:samsung 840 pro 128gb
hhd:2 caviar black 640 sata II on raid 0
sound:soundblaster x-fi titanium fatality
monitor:LG flatron E2250V 22''
os:win 7 ultimate 64bit


I want to replace hyper evo with Noctua NH-U14S CPU Cooler,i still have temps max 82c stable at full load using intelburntest and i want to drop the temps more. So i have a problem.I think Noctua will cover the top pci express x1 that i already use for soundblaster x-fi titanium fatality,so the next pci x16 (the first one )is occupied by my 660 oc gtx and covers the second pci express x1.On the third pci express x1 i don't want to use it because i think it will block the airflow to my card.The big question is if i use the bottom one pci express x16 for my soundblaster x-fi titanium fatality will effect the speed of my VGA?
i know that the pci express x16 operate like x16,x8,x4 when put a second or third VGA but this is soundcard.What is your opinion?I don't want to downgrade the speed of the 660 because i use the bottom one pci express x16 for the soundcard.Also if someone can verify that Noctua NH-U14S is blocking the first pci express x1 in order not to mess around things whould be great.

Good, since the sound decibel is very low, you probably you can maxed out the fan performance(draw in more air - side). Hope to see your result when using it.

Those 2 extra fans i'll plug them directly to my mobo right?They have 3 pin but my mobo has a 4 pin,that's not a problem i guess and How i change the fan performance?
Any news will be posted here monday afternoon

That definitely good, how about the noise level anyway?
Push/pull Configuration on Noctua U14S may also help you push little more to 4.2 or 4.3GHz maybe, just guess. Anyway that definitely a good result.

Hi my firend there's no sound prob,my pc is silent enough,i'm not planing to overclocking yet,but if i do so i wil ask you how to do it,you see i jumped for 1156 to 1150 socket and things are a bit different now.I also manage my cables better
