Custom loop temps.

[MayorPotatoSalad]

I built a water cooled computer at the start of this year with a 4790k and a GTX 980. It ran great and I have continued tinkering it too this day and it has evolved quite a bit. Its current revision, photo and specs down below, I am a little confused by the temperatures. At idle both my 4790k and GTX 980 run below 30 degrees which I am fine with as the ambient temperature here is around 25C anyway. However, once under load my CPU temps can reach up to the low 70s and my GPU (overclocked to 1530Mhz) reaches high 60s. I don't believe my temps have ever been this poor and am unsure whether its just the hot Australian summer or if the cooling performance of my loop is degrading. It appears to me that my radiators are not doing a sufficient job of dissipating the heat of my loop for some reason as my coolant temps (monitored through a bitspower probe in the pump block) reach about 55 degrees. 

 

Could it be also because my coolant needs replacing? I am using Alphacool CKC and have been using it for about 9 months.

 

Any suggestions as to what it could be would be great. Thanks.

Is the PC getting enough airflow? The back of it looks pretty block off there. So the hot air being pumped out of the raidiators could just be sitting around the PC and being sucked back through meaning its not really getting any "fresh" air to cool the system.

Nice purple build, but as for temps those initial temps aren't bad and you do have more than enough rad space for cooling, but how far are you overclocking everything?

 

Also just as a test to make sure it's not an airflow problem take off the top panels of the case to see if temps drop significantly.

The photo is on the side so that is actually the top of the case haha

Will do, thanks for the suggestion

It looks like it got shoved in the corner too much. Try bringing it into an open space and testing it.

Also you need to make sure your room isn't increasing in temps too much.

High 50s low 60s is what I would expect on both

55C coolant temps is really really bad.

I can't get my coolant temp over 43C

Just tested without the top or side panels on and temps dropped by nearly 10 degrees. Might do a bit of modding to allow for more airflow haha My case is an Enthoo Evolv, great case, but shit airflow it would appear

My computer is in a very open space, sorry, the forum rotated the photo so it is hard to get an idea of the space. Just tested with my top and front panel off and therefore unrestricted airflow and temps dropped nearly 10 degrees on both CPU and GPU.

10 lower would be more reasonable... What case is that?

The front in particular looks fairly restrictive.

Phantex Enthoo Evolv ATX. Amazing case, absolutely love it, but yeah, air flow is not amazing. http://www.phanteks.com/Enthoo-Evolv-ATX.html

Yeah it seems like the top panel isn't giving much airflow out of the case other than the side vents on it.

There are large gaps on either end as well

That's a plus

Nice looking computer!

Coolant age won't change its heat transferring ability unless you had crap growing and circulating around your system clogging things. Though then it would be the clogs not the coolant that is the problem.

Also could you edit your OP with a better pic? Far enough back to not cut off the front of the case and rotated properly would help people not be confused. I'm guessing you used an iPhone? They seem to not rotate pics properly so take the photo in portrait and crop it before uploading rather than using a landscape shot. Should fix the problem.

Been trying to upload a new photo but just keeps rotating them. I am using a Galaxy S5 and it appears to be the forum rotating them and not me. I even tried to pre-rotate the photo in the opposite direction but it still seems to upload it on the same side haha Will keep trying.

[boarder2k7]

Odd, I have a GS5 too and I only seem to have that problem with people sending me iPhone pics.

Which orientation are you holding your phone in? Maybe try re saving on the computer and uploading from there?
