Thats a high ambiant.Mines usually no more than 20ish.
Yeah, exactly why your having a hard time keeping those temps low. No offense but something you should have considered from the start. Granted the loop looks great man!
47c, you live in the desert or what?
And overclocked chips need big heat transfer. I have a triple and a single rad, granted two cards than run hot also. It goes just as high as 65° above 1.45v, thats why a seperate loop is due soon.
A dual rad, especially as thin as yours can have a hard time dealing with those temps.
that reservoir is as big as your ambient temp. i'll be honest i'm not a fan of your case I really don't like Apevia cases. this will be a great learning experience your loop is much better than mine was I had a external fish tank pump, old grout bucket for a reservoir, modified auto radiator I got from a mcse class mate and some no name tubing from the local hardware store but this was when liquid cooling market was born. I have always setup my loops in Reservoir -> Pump -> CPU -> Radiator -> Reservoir. forget Push and Pull, Push and Pull favors High Speed Fans and since High Speed Fans favor Thick Radiators with large Fin Density stick with Low Speed Fans in Pull until you can purchase a new Radiator. lol at smoke break when you have a smoke make sure you play some punch-out.
Asylum - ambient means the air temp in the room. 47c is about 117f! And that's one HELL of an overclock!!!
I have a triple rad and see idle temps around 38c and load temps up to 52c with my E6600 CPU only at 3.2 right now (still messing with dividers and shit). Air temp is about 24c (75f).
What are you using for temp monitor?
Bumblebee has good points, good airflow through the rad is as important as it is with an air cooler.
Sorry guys thought he meant idle temps!!
The temps in my house stay around 70f
Dude put the rad inside more awesome/ better
Wont fit inside!!
Plus that would just make temps hotter!!
3 suggestions -
try water wetter - it will drop temps by a bit - by reducing the surface tension of the water (i.e. making it absorb heat better)
Put your fans in pull mode, instead of push (mount the fans outside of the case to the rad.) Pull mode works better with <75CFM fans.
3 - check the mounting of the waterblock, and check the flatness of your chip. You may need to lap that sucker.
Last question - what are you using to load the chip?
yeah your chip should be barely making it past 50C, at max.
Try to reverse the fans for a second so that they are blowing IN to the case through the rad.. If that makes a difference then you have an airflow problem, which is easy to fix.
I used to have those same exact components with the E8500 at 4.1Ghz 1.42V It should be performing alot better - we can fix it.
I'm using a 120.2 with my fans in pull mode,i have also put two fan frames twixt fan and radiator,seems to make a differance.
yeah the shrouds make a big difference, always a good idea if you got the space.
You reckon it would make any differance if i put two more frames/fans on in push/pull mode?
Ill try that out and see what happens!!
It would. Martin's Liquid lab shows just the one 25MM-30MM shroud can improve t-delta by 10-15% - I don't know how much a second shroud would improve it by - never tried it since it would make cleaning dust out of the rad a PITA.
It would make cleaning a pita,as it is now,i just take the side off and hoover the rad.Push pull is apparently better though,i might try it.
I tried the push pull method with 2 more fans on the outside and it only made 1c difference!!
Starting to think this rad or block is crap.
One or the other!!
Started out at 43c this morning when i first turned it on!!
Didnt take it long to go to 47c at idle!!
Ive checked the block 3 different times and the contact seems fine!!
Is this with your processor at stock?
No its overclocked...E8600 @ 4.25ghz 1.38 volts 47c @ idle and 65c @ load!!
I got that with my air cooler!!
is the block flat?
i would go through the list
1 make sure its on securely
2 make sure its flat like phanbuey said you may need to lap it
Most intel ihs are not flat,you can either try lapping the cpu,or use the fat ring that came with the apogee gt to bow th block.I just lapped my E6750 as the base on the gt is pretty flat.
I changed flow direction and moved some fans around!!
Changed to pure water and got about 3c difference!!
The block looks to be flat but ill get a blade from work and check it and the CPU tomarrow!!
Looks like to me the rads not doing a good job!!
You can tell if its the rad by touching the rad during load. Rads that are overloaded will be hot to the touch... that MCR 220 is one of the better rads around, and I almost guarantee that it is not the rad.
That same rad cooled my OC'd Q6600 at 1.52V to below 55C.
If you're BOOTING at 43C, then you have a contact issue. You should be booting at mid-20C.
Buy water wetter and add it to the loop. - it cools even better than pure water.
