High idle temps with X73 Kraken on Ryzen 7 3700X

Recommended Posts

Posted · Original PosterOP

Hi. Before you say anything I know it's a common subject and I've been looking for a solution for some time. The thing is, I don't really want to mess with the voltage in BIOS as I just simply want my stuff to work without doing that. From what I've seen it's like a lottery to me. Some people have their 3700x cooled to 30-40°C with stock coolers and the rest - like me - have issues caused by God knows what.

So basically I got myself a newly bought build and am already struggling with the temps of my CPU. At first I was using a stock cooler Wraith Prism and the idle temps were jumping from 50°C to 70°C. Couldn't quite figure out why. After some research and reapplying of the thermal paste I decided to buy NZXT Kraken X73 360. It's a bit of an overkill if I'm not going to overclock anything, I know, but I can still refund it within 10 days. After setting it up the temps are flactuating between 50-60°C idle most of the time at the ~2150 RPM of the fans. In the Prime95 stress test it goes up to 81°C after 10 minutes. In NZXT Cam I have it set on performence mode, configured for liquid temps. I'm using AMD Balanced plan. The thermal paste I used is be quiet! DC1 and that's the only one I used for both stock and an aio cooling.

All drivers are up to date. (chipset, BIOS, etc.)

It's surely better than the Wraith Prism, but I'm just not quite happy with the temps in general. Others having this setup say that the temps won't go higher than 65-75°C. X73's suppose to be more efficient, right? I find these temps quite concerning as I don't want to kill my cpu with such idle temps on a long run.

It's called the silicon lottery, sounds like you may have got a poor draw. Good news is your idle temps won't hurt the cpu.
Make sure power saving features like amd cool n quiet are enabled in the bios

Some thoughts I'm having: 

1. Make sure the AIO has the pump set to 100% - or using the AIO pump header on your motherboard
2. Are fans on the radiator getting "suffocated" from a close fan filter?
3a. Right mounting pressure on the CPU
3b. Is the CPU IHS bent a little? Find a peace of glas, put it with the IHS down first, try and spin it. If it keeps spining, the IHS is bent and will not make proper contact with cooler - can be filed down/flat with sandpaper (Jayztwocents have shown this)

pretty normal behavior and normal idle temps

not familiar with prime95, heard it loads CPU more than anything else, i use Cinebench R20 on loop

that said, 81c is high for your CPU, esp stock settings, but not sure if it's normal behaviour for prime95

 

what voltage does your CPU run at? monitor using Ryzen Master

those temps are high, but not alarmingly high

so it's fine to use as is, but would be better to find out why it's running at higher temps than expected.


Things I need help with: *new* What can Facebook do to me? Privacy Inquiries

Spoiler

 

 

I hate Intel's pricing, Ryzen's weird quirks, Nvidia's pricing, and Radeon GPUs in general

 

Spoiler

 

Products I like:

Spoiler

Sony Xperia Z1 / Z2 / 10 ii, Asus Strix 970 / 1070, Samsung SSD, WD HDD, Corsair PSUs (AX, RM, CX(grey)), GeForce GPU, NZXT N450/S340, be quiet! Coolers, G.Skill Trident RAM, Logitech M525, Logitech G440, Razer Deathadder Elite

 

Products I hate:

Spoiler

Xperia Z3, XiaoMi 5c, Radeon GPUs, Razer Audio Products, any bloatwares

 

Companies I absolutely adore: (and hope it stays that way)

Spoiler

be quiet! - sent me AM4 mounting for my DRP3 even though it's way past the timeframe stated, no questions asked

Corsair - very good RMA experience, absolutely recommend

 

Companies I hate:

Spoiler

Nvidia, Intel, Apple, TMT (Thundermatch, a retailer)

 

Personal Blacklisted Companies:

Spoiler

Acer: shit tier quality products, shit tier customer service thus far, they "tried" to solve my issue but they arent really doing anything but delaying and delaying. (on-going case since July)

Gigabyte: horrible customer service (gigabyte had literally 0 customer service, asked me to go to retailer with NO WAY to email them about a question) but at least they fixed my shit in ONE MONTH (would probably take me 1 hour to fix if they let me email them)

XiaoMi Phones: built like a tank but the software is buggy as all hell

Seagate HDD: had too many dead seagate drives

Kingston SSD: 300V controller swap thingy

Razer (except their mouse)

 

Remember, just because I had good/bad experiences with these companies/product, doesn't mean you will have similar experiences too. I would still recommend these products if they made sense for your needs, but I'll add a disclaimer of my experience if it's relevant. Feel free to DM me asking why they are where they are.

Prime95 makes the CPU runs 10C+ hotter than Cinebench R20, easy.

,In the same boat switch from an a33 esports with high idle temp around 60 with r5 1600. Thought is was because of the heatpipes on the cooler was highly uneven. But with an h100i v2 same problem.  High ideal temps and with asus motherboard it makes it worse as critical cpu temp 75c it forces fans to 100%.full pump speed and fan speed works to keep temps under 70 No matter what I do with the fan setting it always up and down and up and down just opening a bowser. Something isn't adding up here.

50-60C at idle won't damage the CPU. Many graphics cards have zero-fan until the temperature reaches 55 - 60C.

 

What is idling? If your PC still have a bunch of things opened, CPU at 3 - 5%? What is the temperature if you close everything, and the CPU only at 0-1% load?

 

Open Ryzen Master. when the system is idling, most of the cores should be 'sleeping'. Only one or two cores handle the background tasks. Yes, those one, two cores jump up and down a lot in term of clock speed. And the temperature you see is referring to those one/two cores, not the entire CPU. Look a the power draw, 10-15w?

To dissipate 10-15w with a 360mm radiator. You can turn off the fans, probably won't make a difference to the temperature. So, either there is a problem transferring the heat from the CPU die to IHS to the cold plate of the cooler. Or there is a bunch of things working in the back ground using a lot of power. If you see 30, 40w+ when in idling. That will explain the higher than normal temperature.

 

This is my R5 3600 4.4GHz in idle.

Set the fans so that unless the CPU jumps pass 55C, they stay at idle speed. So the fans won't whine up and down by just opening a browser.

Temperatures seem within normal operating conditions. If you trying to get the load temps lower maybe try removing the glass front panel or use a case with mesh front. Are the fans and radiator both mounted in the main compartment that is not directly in front of the glass front?
