R7 3700x temps

[OdivValknir]

I am sure this topic has been beat to death, I've been noticing my cpu is still idling rather high even after flashing F5b bios. I have a custom loop water cooled rig, which manages to keep my asus strix 2080ti to 50c under full RTX load. Yet it cannot seem to keep my 3700x under even constant temps at idle, usually see somewhere between 33c and 55c at idle, and actually had a thermal shutdown the other day while playing a semi older game (dying light). I'm a bit curious why I'm STILL having so many issues with temps on this thing. Are there settings in bios I need to change or are we still going with AMDs explanation of "Thats what it's supposed to do"

Are you running default BIOS settings and Ryzen Balanced power plan in windows?

Yes, only thing not default is XMP

[glenalz81]

As much as it sucks with a custom loop but have you re-seated and or re-pasted the chip?

[OdivValknir]

No, I've been hoping to avoid that. Though I may be able to get it without draining the loop. I've really been dreading having to do that. It shouldn't need any reseating or repaste. Though with these temps I guess it's a possibility.

Do you know your water temperature at idle?

[DoctorNick]

Do you run with auto overclock aka PBO? What is your thermal`/current limit set to. Maybe it's too high. CPU boosting way out of temp limit and crashing? 

[OdivValknir]

Water temp at idle is around 39c

 

I haven't changed any settings in BIOS other than XMP for the RAM, I haven't really looked into what settings others are changing and what is standard for these chips.

Do you have pics of your cooling setup?

 

[OdivValknir]

Routing is 

pump > gpu > cpu > rad > res > pump

[OdivValknir]

I ran it that way because I figured the 2080ti would generate more heat than the 3700x. Under load, the gpu stays around 50-55c CONSTANT. The cpu fluctuates even idle, and I actually had a thermal shutdown the other day.

[glenalz81]

Looks nice

 

What does the GPU idle at?

 

Might be worth trying Pump> Rad> CPU> GPU> Res

Since you have soft tubing, the quickest way to convince us you have adequate mounting is to take off your CPU block and send a picture of the thermal paste spread on both the IHS and the waterblock

I guess I may have to do that. I wont have time till this weekend though. I really hate to go messing with the damn loop.

As a general comment, 39 degrees is fairly warm for idle fluid temperature, even considering it looks like an SE radiator from EK?

It's actually a PE, so it shouldn't be that warm. The case is a TT view 71 So the air flow in the case isn't terrible. I could probably use push/pull on the rad, just didn't have the money for 3 more fans by the time I finished the build.

 

I actually just took a look at icue, and its showing temp to be 28.5 at idle currently. So maybe I was off when I said idle water temp earlier.

Maybe until you have this sorted you could run the fan/radiator outside the case just to rule out some airflow issue.

gpu idle is steady at 30c, cpu idle moves between 40-50c

That's pretty high. Seeing CPU temps 16°C higher than the water for a second or two should really be expected with a water temp like yours.

Do you monitor the CPU temp with HWinfo or Ryzen Master?

 

In HWinfo, the core temp is the hottest core. So when, say Windows doing update in the back ground,  a few cores will spike to 55C. But the rest of the cores are 30C because it's idling. When you use Ryzen Master. The temp is all cores average. Then the idle temp is very stable. My 3900X with a 280 rad stays at 32-34C when idling.

I think I may have mis typed. I checked iCue and its showing water temp at 28.5c

I checked that earlier, and hwinfo and ryzen master are reporting same temps.

I guess I'm gonna go ahead and try to remove the water block and check for proper fitment, and seating. Hell I even used a decent thermal paste, I got a tube of cryonaut with the block if I remember correctly.
