Low Idle High Load

[NXLTrauma25]

Hey first post here but i have a problem...I think...with my new water cooling setup

previous air cooling put my 2.7 ghz 1.45 volt 4800x2 at 40-42 idle and 50-55 load

my water cooling setup...Danger Den TDX cpu block and maze5 gpu block (7800gtx)...black ice GTX xtreme 240 rad with 2 silenx 74 cfm fans pulling air through radiator (rad and fans are located oustide case) swiftech mcp655 pump and XPS res

At stock speeds and stock voltage this put my cpu at 29 degrees idle and high 30s to mid 40s load and my gpu sat around 36 degresss idle and 45-55 load

when the cpu is bumped up to its above speed at 1.45 V and 2700 mhz the idle hits 33 degrees and the gpu jumps up a degree or 2...which seems fine however just as it was when it was stock...the load temp is about 20 degrees higher

I see alot of peple with higher clocks on dual cores then me with way more voltage and high voltage on their video cards and are not even breaking 40 to 45 on load temps and idle around high 20s low 30s

some of them dont even see an increase of more then 4 degrees at full load over idle

is this a problem or normal among setups sometimes

house temp is about 70 degrees F and case thermometer reads mid 80s F

forgot to mention also...is it a possibility that a majority of the heat problem is cause the fans are pulling instead of pushing...my rad sits on top of the case about 2 inchies away from top ...ontop of a swiftech radbox and outside of running 4 fans the 2 fans will have to remain on the bottom and pull because they are also asisting in the mounting since the radbox only fits on the top 120 mount so I wanted the longest screws with the most support thus the screw running through the radbox and one of the fans and into the rad so that it was sturdy( I am sure that if i kept them on the bottom there would not be enough air between them and the case to effectively push air through the rad that would be as cool as pulling it through the rad)

I wouldnt beleive everything you read and would question with what and where such a low delta Temp was measured. It sure as hell wasnt the core temps unless they were cooling with liquid nitrogen. (or had a larger rad and higher CFM fans than your setup)

Pull better than push, in general. Pull with shroud unarguably the best. I tried to visualize your rad setup but could not, As long as you are providing cool ambient air to the rad you are good to go and your temps sound normal to me but I havent overclocked an AMD since the Barton M.

WC will decrease your temps a lot at idle but usually not so much at load on a high overclock, and maybe give you a little more overclock. Mainly you dont have to listen to screaming fans.

well picture a normal computer case with wv...except picture the tubing coming out the back and up to a rad sitting on top of the case...about an inch off of it

I took my temps with the program Everest and it read 30 idle and about 37-40 load

that seems alot better...plus it doesnt jump from 40 to 29 to 48 to 35 or anything like that like speed fan and all does which makes me think it is way more accurate

Use coretemp... It's the only reliable one.

Intel TAT is also a good option.

 

[NXLTrauma25]

core temp reports when im overclocked that the temp on core 2 is about 301 idle and 40 load and core 0 is 37 idle 50 load

First... Welcome to the [H]ardForums NXL!

Secondly... I'm fairly new to Watercooling myself, but have done a lot of research and reading up on water cooling, and its issues. Correct me if I'm wrong (and I probably am), but isn't the BI Xtreme rads meant for high flow fans, where the Stealth series was for low cfms?

Mainly you dont have to listen to screaming fans.

Noise levels have dropped alot in my office since I now have all 3 of my systems running on water instead of air. Even though one of the systems isn't running cooler than it was on AIR, it is running much much quieter.

In the 30 months that I have postponed watercooling any of my computers, and doing lots of reading, I have read about various problems people have had with their watercooling setups. In situations like yours (or very similar), where the idle temps have been lowered over air cooling, but load temps are higher, it seems to me that the common item that all the fingers point to is the radiator. Either your radiator is not sufficient (large enough) for your system, or the air flow through it isn't up to par during load (low cfm fans on a rad designed for high cfm - or poorly sealed connection between fans and rad). You also have to take into consideration that you also have a GPU in your watercooling loop.

In the end, you can't make comparisons between your system and someone else's, even if they are very similar. Just like people shouldn't compare overclocks with others who have similar equipment.... in overclocking YMMV. You should be happy with your system as long at it achieves what you originally set out to do (with watercooling, that would be to reduce noise levels and/or increase overclocks). As long as your temps are within "specs", I wouldn't fret too much about it.

Good Luck

Thanks for the welcoming

These fans seem to be flowing decent air

the thing that boggles my mind right now though is the block on both the gpu and cpu is cool to touch ...not hot like the temps are stating

however



i guess the question now is...is the program Everest the one I should believe as this is giving me the most believeable temps ...considering that any program that gives you 48 degrees one scond and 40 the next.......

everest seems to remain within 5-10 degrees between idle and load and doesnt fluxuate as much as othewr programs



what cfm fans should be put on the xtremes...i thought 75 was good enough...and from what I have read putting 4 fans on a rad (2 on each side) actually decreased performace of the rad in alot of cases over having just 2 pulling like I do

 

[NXLTrauma25]

Forgot to mention I also put a huge massive house fan overtop of the rad blowing air through in order to just see what happened....temps didnt drop at all until I opened the window and let some cool air in


I believe ambient temp in the house is playing a large role

Also the oinly temps that changed were those read by everest....neither core temp or speed fan saw a change

sorry for the bad image quality...but basically there is a couple inches between case top and fans/rad

just wanted to give an idea of how that is setup
