Is my custom loop temperature ok?

I just wanted to ask if you though my temps of my coolant were ok,
The coolest temp is measured with a temp sensor that is in the loop.

The specs are
i7 8700k stock speeds
gigabyte gtx 1080 stock speeds

The gpu and cpu are water-cooled and the cpu block is a full board block.
The fans are ML120s running at 100% with the temps I am about to tell you but as it gets cooler they are set to run at about 60%. at this temp the pump is set to run at 80% otherwise it just gets annoyingly loud

The order of the loop is
PUMP>GPU>CPU>TEMP SENSOR>RAD 1>RAD 2>PUMP

That is the only order I can have it in this case which is a Lian Li PC Q37

The temps are while running Prime 95 max heat and furmark GPU stress tester 46.2 degrees for the water temp. 52 degrees for the gpu. 86 degrees for the cpu package. Room temp is 22 degrees. When the pc idles the water temp is about 24-25

The cpu paste is well applied as it idles fine with all cores at similar temps.
there is 1 litre of coolant in the loop

What I have thought is that because of where the temps sensor is that is why it is so high so I ordered another to go after the rads just to see. Could you tell me if this theory is a good one?


Could I just know if these temps are reasonable with the parts all running 100% which will be higher than they will get run in games?
Also does the temps seem high because it has the heat from the water going through it before the water gets to the rads

As long as the coolant stays under, I think 60C you're all right, that's when the pumps will start to complain. You'll have to check your pumps high temp though. Personally, I think for a stock system your temps are a little high, 10C over coolant temp is fine for a GPU, but 86C is kinda hot for a stock intel chip. What version of Prime95 are you running, they are not all equal, some stress the chips a lot more than others, so much so that you shouldn't test with them. Either way though, you're right that under normal gaming circumstances you won't hit those temps.

Yeah it is 60 degrees for my pump. It is the non avx prime 95. When I test just the cpu on its own it runs a lot cooler but I put the high temp down to it being after the gpu and it also having prime 95 on the maximum heat setting and furmark running at the same time. Also the temps I gave are after an 1hour of testing.

I did hear the 8700k runs hot... Still, sounds too hot for stock. Have you tried undervolting it? sometimes they can eat a lot more voltage at stock than they really need.
