Hey. I'm Remilia.
I'm having issues with my cpu temps. I'm getting lower 80s Celsius on my i7 920 cpu. I'm not gaming on it when those temps are detected. it usually runs hotter when playing destiny 2 obviously. But lower 80s on low to idle use is NOT GOOD!! my vreg is usually lower 50s and system temps usually in the lower 30s all under idle. my board and cpu are on a single  custom loop and i reapplied thermal paste on my cpu and it helped a little but not enough to be below the 80s. my pump according to the seller of the cooling kit is a .15 psi. I know it's puny but would a new pump be the complete fix to my problem???? 
 
is this a good solution??
Phobya DC12-260 12V Water Cooling Pump

My package is 130 Watts i applied fresh thermal paste the block is on as tight as is safely possible without over tightening and and the entire cooling system is brand new no clogging or anything. It is generic branded though. One Evga rep blamed my cpu saying it’s “going bad or is already bad. Call Intel for assistance” I even bought wider tubes cause the ones it came with are smaller. I now have 3/8 Id by 1/2 od primochill tubing. I’m sure I did everything right as far as hardware and setup. Any thoughts???

Welcome to the EVGA Forums 

Sounds like your lines are connected backwards to the CPU block.
 
Confirm:
 
1) Pressure from pump is connected to inlet of CPU block
 
2) Pump is not cavitating
 
3) Air has been bled throughout the loop.  (Usually by tipping while the pump is running)
 
4) CPU block is not clogged
 
5) Unlikely as it sounds, protective cover removed from CPU block before mounting --> (It has happened before)
 
 

 
Trust me, my first custom loop.... Horrendous amount of hours spent troubleshooting and testing was definitely a concern for unhealthy obsession. All for a clear plastic sticker on the cooling plate  So yes, that has happened before :P

I just checked my loop and noticed something hilarious. Not. My loop is getting next to 0 flow from the pump to motherboard waterblock section absolutely zippo nada big goose egg flow on the motherboard block to cpu block cpu block to radiator radiator to pump is next to zero. flow does go on the bottom halves of the tubes on radiator to pump and the pump to mobo waterblock sections. but it looks like on those sections it struggles to push it all the way through the rest of the loop like its a bicyclist trying to bike up a 85% grade hill but ending up falling back down to the bottom of the hill. everything looks unclogged and whatnot. again EVERY part of the cooling system is NEW. I'm thinking a new stronger pump might be what wil fix this.
 
any thoughts?????

Hello Remilia, 
 
 
Could definitely be that, but when it comes to water cooling (in my experience), CPU water blocks and GPU water blocks I typically buy high end. It could be a pump issue given the smaller pump that you have, but it could also be a bottleneck due to manufacturing (or designing) of the waterblock. Would recommend taking apart the loop and doing an initial flush and thorough cleaning. 
 
 
 
 
 
 

Look at my Build in my Signature  Nibbler & my Mods Rigs page
 
I use (1) D5 pump for 3 GPU, CPU, 1-360 radiator & 1-420 radiator
 
These loops do Not run at a very high pressure, most blocks will leak under more than a few pounds of pressure
 
Air "in the pump" will cause cavitation and a low flow with no pressure.

the pump i have now is generic so i'm dubious of its quality/performance. also its a .15m and the phobya one i showed is 2.5m. is this the issue?? every other idea i tested and tried i think. unless i'm missing something but i'm positive i tried what all ideas you suggest that are relevant to my particular setup.

i don't have part numbers for the pump reservoir barbs etc. as their all third party generic crap. but the tubing is primochill 3/8 id 1/2 od and the mans are 120mm . two of them on a generic dual bay radiator. i can't afford high end as i'm a freaking cashier at (removed) mcdonalds. so this build already cost months and months of paychecks to get what i have now. so better gpus than 590s is out and gtx 10 is a pipedream. and 20 series?!? forget that!! the managers at mcdonalds can't afford those. trust me i know. we talk. however a new pump i can afford. 
 
do you think i should go ahead and get one?
will that fix anything?

I just checked to see if the protective cover was on the cpu waterblock still and would you believe it?!? It was! I removed it and 40 degrees drop difference. Like night and day. Crisis averted....so far at least
Keeping an eye on it for now just to be sure. Note I’m playing destiny 2 on it now and I’m running low 40s Celsius about 42 ish
