overheating, 50 degrees C when idle

tim967 · 15 Aug 2012 at 21:45

Hey guys recently upgraded my watercooling so it now has a 240 and a 360 radiator for the CPU both have push pull set up so am using 10 fans, the cpu is now running at about 50 degrees C when it's idle, any ideas why? I tried applying the paste but still no change, 7 of the fans are running through the nzxt switch 810's fan board which is powered by a single Molex so those are running at about 400 rpm, could this be why? If so could anybody recommend a fan controller that will let them run at full rpm and reasonably cheap?

If anyone has any other ideas I can try please let me know

Many thanks!

Could help with knowing what's in your rig. But sounds to me you have a blockage somewhere or your block isn't seated correctly. And no you have so many fans and rad area that running them at that speed will not have much effect. In fact I would say you have gone overkill with that much rad to cool the cpu, but that's another story!

i did intend to watercool my gfx card in the same loop but realised i bought the wrong waterblock for it so its just the cpu for now, im assuming i need a fan controller, could you reccommend one that will be able to control 8 fans?

Unplug all the fans and test the idle temp without them

you may have gunk build up in your block(s); strip it down and give it a clean

it does look like there is something there that shouldnt be, will it void my warranty though on the block?

if they've got a sticker on the side saying void if removed, yes

but, unless you're really clumsy, it'll go back together fine

ahh ok ill take a look when i get back from work thanks

is there anything small and breakable that i should take extra care with? and what would you reccommend cleaning it with? or is water ok?

what block have you got? tbh when i've cleaned mine, i've just used a piece of tissue and gave it a rinse after. if you've got staining from dye, some people like to use ketchup and an old toothbrush, but i've never needed to do that

tim967 · 16 Aug 2012 at 13:06

its the one that comes with the ek 240 ltx kit, never heard of using ketchup before? i think ill stick to tissue too. i did have the mayhem aurora with the silver bits and im wondering if they've got stuck in it somehow

mainly it's the dye/other additives (in the dye already or added after) that leach the plasticiser out of the hose. it forms a snot-like gunk, usually in the impingement plate (it's a small gap so easily gathers), which blocks the gaps and thus reduces flow. i found my temps went up about 4-5*C before i cleaned mine out before.
