Water cooled, high temp when OCing

turbojosrt4 · Sep 25, 2013

]Hello everyone,
Just joined but I been a long time lurker, So the problem i'm having is that I just build this rig a month ago. I been fight this water cooling system since. On stock speed (4.1ghz)my Idle is around 38c at the socket and about 21c at the cores. Using speedfan, coretemp programs. When I benchmark using prime95 for about 30mins. My socket is around 50c with 38c cores. Yesterday I OC to 4.4ghz(mild to what others set to)my socket ran at 61c and 48c cores.

The temp seem too high for the water system I have install even at idle. The system feels some what cool, even when at 61c. The water block was a little warm and the water in the res was cool, so were the hoses. I have a sentry 2 fan controller and even went as far as putting one of the sensors inside the rez (maybe that was stupid)which read 32c during the 61c OC benchmark.

I reset the water block 3 times and reapplied the thermal paste. Also got all the air out of the system. i'm lost......

Hi. First thing I would do is try another App such as HW Monitor and see what readings you get with that.

have u bleed the air from ur lines?air bubbles can cause it to heat a bit.

coastie65 :

just downloaded it. idling and stock speed. temp1 shows 38c and temp2 30c

kookie3010 :

yes. i believe so. i tilted the rad straight up and down so the air traveled to the top and then shook it

turbojosrt4 · Sep 29, 2013

I changed out the waterblock to a koolance 380a and installed 6 corsair sp120 on the rad

look what i found on the old block

expensive lesson

coastie65 · Sep 29, 2013

WHEW !!!! That could cause some issues. Expensive lesson indeed.

kookie3010 · Sep 29, 2013

Wow.that terrifies me just to think what will happen if you didnt notice that.

What are you pumping green Jello?

Something is seriously wrong!

Obviously!

But what?

coastie65 · Sep 30, 2013

Not familiar with that type of cooling, but it would appear that the cooling solution is congealing. The big question is why? Kind of reminds me of my arteries, which didn't go well either.

4Ryan6 · Sep 30, 2013

Looks like Slimer! Call Ghostbusters!

JKing, but seriously what coolant is that, I really would like to know as a reference of what not to use?

alphacools CKC coolant with mayhems dye.
edit. that pic was after i removed almost half to see what it was

coastie65 · Sep 30, 2013

Well, that certainly explains the cooling issue. So far I haven't gone to water cooling. My air cooler does well and it isn't even one of the better ones. It is a Gelid Tranquillo that seems to work well and I am OC'd to 4.6 Ghz.

FYI; I've been using plain steam distilled water and siphoning off a 3 reservoir filling every couple of months to keep it fresh, my blocks are clean, no residue, no caustic problems.

Do you think distilled water is better at cooling then a coolant?

i use to mix both water and coolant in my rig.so far no problem.temp are low and it doesn't heat up much.now i use
a new case so i am back to air cooling

turbojosrt4 :

Yes I do!

I used additives in the past but they caused problems.

Nothing I experienced in the past compares to what you've just experienced though.

err..maybe distilled water with a few drops of bleach n vinegar?

Y0GI · Oct 3, 2013

schmuckley :

Bleach and vinegar are a bad combination. Bleach has a high pH (very basic) and vinegar has a low pH (acidic) so the 2 will react to form salts, which are bad!

humm.. still want to drop the idle about 8 degrees more on idle. Which right now the CPU is 8-10 more over ambient

turbojosrt4 · Oct 5, 2013

A little more info
OC 8350 at 4.7ghz with 1.43v max temp is at 62c. With 1 hour of prime95 (idle aorund 35-39c) ambient around 24-27
i would like to get that down to 55c..
I'm going for the 5.0ghz club

coastie65 · Oct 5, 2013

With the TDP of those things and the clocks you are running and want to run, you may be hard pressed to get them down but so far. The ambient temp doesn't help much either.

turbojosrt4 · Oct 8, 2013

Well bought some distilled water today. Going to flush it out tomorrow and maybe take apart the water block to check for build up

So just making sure, I don't use any additives when running water?
