Hello, i have recently built my PC, i have only watercooled my cpu and at stock speed i was getting high 70's on intel burn test (max Settings). everything seems fine except these temps, do you guys have a suggestions as this is my first build, be ready for noobish questions :)

i5 4670k@stock
7970 matrix platinum
Gigabyte z87x-ud3h
Corsair vengeance 1866mhz
alphacool xt45 240mm rad
EK dcp 2.2 Pump/res
EK clean csq Nickel cpu block
 
Thats high for watercooled and at stock.

I assume your system is fully purged of air and no air locks, cpu cooler mounted properly.
 
Yeah, check you have the it right way. the inlet hole in the centre hole on the block, and the outlet hole is the hole on the edge of the block. I made that error and when I swapped it over I saw about 12-15 degree improvements.

If you have it correct already, maybe worth delidding and reapplying the lid with liquid metal. Intel screwed up the paste usage on Ivybridge and Haswell chips.
 
ive changed it now but idle temps are 25-30 but load is still very high around 70's, do you guys think i may have done something wrong with the thermal paste ?
 
I have zero knowledge of water cooling, but I do know that you need a small rice grain/pea sized blob of paste.
 
i have air bubbles in every part of the loop, will this effect temperatures a lot, i have some even in the block and any tips on how i can get rid of them
 
Open your res and gently rock you case back and forth it will dislodge the air and allow to be carried round to the res.

and don't fill your res to the brim or the air will have no place to escape some times its usefull to run it with the lid open for a few hours also
 
You can pinch the pipes carefully too to dislodge trapped bubbles,they will naturally want to rise to the top
 
take your block off your cpu....clean it..... reapply paste and reseat it as well if you don't see improvements when you have got rid of most the air. My block when i first built didn't quite sit right and i had to do this but from the sounds of it air is your problem
 
I think I'll try getting rid of the air first before removing the block but can air really have a significant effect on temperature ?

that's not as much air as i thought... you sure your pump is running? :D and check block is seated right. Those temps really are not right. What were you getting before you put block on it?
 
You might be drawing air in, try making sure the seal (o-ring) between pump and res is tight or not (nipped) it could be drawing air in which will degrade the pump performance. Although you'd know because the pump would sound louder or pulsing.

Although if the o-ring was nipped, it would probably show by leakage....

Were I supposed to do this when setting up the res/pump as I out the fittings in and started filling the loop, there was also a small spongy thing which came with the res/pump, was this supposed to go in the res ?

Rice, BB, pea, whatever. Some times its too small and it wont cover the whole CPU IHS. I suggest OP put a line down the middle (Along the actual CPU). Or a cross. If you use too much TIM no problem, the pressure from the block will squeeze it out and you'll have a good fit. Dont listen to the (More is less) Because it makes beginners use too little (Which is much worse than too much) and the pressure from the block will spread the paste very well.
