AIO liquid cooler pump failure

[adshidi]

How do I know for sure that my AIO liquid cooler is not functioning? How to tell if pump is failing or the coolant has stuck? Is there any surefire way to tell it for a layman, or should IT guys be called in to check?

 

[animemangamer]

Try touching it while running. When I used to have an AIO there is always a somewhat vibration that let's you know it's running.

First of all....is it cooling properly?

I've had a guy tell me he puts a small piece of fishing line in the clear tube to see how his coolant is flowing.

His AIO will most likely be solid black tubing like what's commonly used.

My 21 months old cooler master seidon 120v v3 cooler is behaving curiously. The 6700k cpu is touching 60°C whenever I am starting the pc by button pressing. But if I restart later the temp is 35°C. Should I RMA it or get a good quality air cooler instead?

Check to see what speed your pump is running at...You should easily be able to see this with Hardware Info, its free and you can download it.....If it is running at speed greater than 1000rpm then at least the pump is pushing water..

It could be as simple as re-applying thermal paste or you could have some sort of blockage but expect low to mid 30's degrees C at idle and around 50 to 60 degrees in games...

 

[adshidi]

AI suite3 is showing water pump to be running at 2400 rpm.the thermal paste has been reapplied recently when I had to replace the motherboard , done by a local IT guy.

 

[Paperdoc]

Why do you ask? Are you seeing high temperatures for the CPU to indicate it is not being cooled properly? Or, are you just wanting to know how to be sure as a preventive measure?

Jumping to 60 degrees at start might be normal...More important is temps at Idle and at load...Mid 50's to 60's in gaming and under 80' degrees in Prime95 or Aida64 should mean CPU is okay...

Paperdoc, I have my MB & PSU replaced recently as MB was malfunctioning. I sent both the PSU and MB back to company and they gave me the replacement. Now, earlier I never used to monitor temps , which I now do. I have an uncanny feeling of damaging my pc as I do a lot editing and vfx works through it, and it is a kind of lifeline for me.

 

[Paperdoc]

If you are worried but not sure if you really have a problem. then start monitoring the CPU and GPU temperatures. For the CPU, look on your mobo's CD for a utility that runs as a Windows app and lets you observe things like CPU temp and fan speeds, etc. For the GPU, Check for a similar feature either as a separate utility on the CD that came with your video card, or already built into its driver tools.

Now then the question is: what is the Normal temp for each of those, and what might be too high? For that, post back here details of what your CPU chip is, and what video card you have. I can't tell you the right temps, but I'm sure others here can. Or, post a new thread asking specifically about what are the "right" temps for each of those items.

 

[adshidi]

Paperdoc, I am monitoring the temps, and as I told before, my cpu is 6700k 4 GHz, and constant 60°C cannot be normal. Why do I have to restart everytime to get back to 35°C? All I want to know what this pattern indicates for the future of my pc?

MERGED QUESTION
Question from adshidi : "CPU heats up at the start, but cools down after restart"

I have a simple thing to know from your experiences. That is - a 6700k cpu sitting on a asus maximus board with an AIO cooler(seidon 120v) atop is hitting 60°C at the start and continuing the heat unless I restart it. After restart it is measuring a normal 35°C . Is it a potential dangerous situation or should I ignore it?

Should BIOS be updated? Is the cooler culprit? Problem in CPU? How do I know?

The pc is only 23 months old. I already had to RMA the PSU and MB, because the pc was booting up but display was blank & fans weren't spinning. The respective companies gave me new parts a month back and it was installed by an IT guy . I never used to monitor temp which I now do. I have a suspicion that cpu heat might be the reason for it.

60'C is not hot
if the fans are working on the aio, then all should be good
Bios should always be updated
Always can be software problem with the program you are measuring it with.

Only update the BIOS if the update is designed to fix the issue you are having. Every time you update the BIOS you risk bricking your board.

Yes Grugbag, I always am wary to update bios, mine is 1701 and latest is 3801, and none talks about heating issue.

A curious problem.

1. 60c. is not dangerous. The processor will slow down or shut off if it detects a dangerous temperature.
That is around 100c.

2. At idle, I expect to see 10-15c. over ambient. 35c. looks about right.
The question is why does it take a restart to get this.

3. Your problem may be that the pump is temperature controlled. It should, I think, be given full voltage from the start.


4. Do not update the bios unless there is a fix for this issue. A bios flash failure can be nasty to recover from.

Geofelt, I agree with you on all points. The question is , should I vary my water pump controll from bios? Currently it is at "disabled", other options are PWM and DC

But AI suite3 is showing the pump to be at 2400 rpm constant speed.

PWM will be a 4 pin connector which manages speed by Pulse Width Modulation.
DC is a 3 pin control which reduces speed by lowering voltage from 12v. to something less.

I am guessing that disabled simply means no speed management and the pump is running at full capability.
I think you have it right to let the pump go at full 2400 rpm.

The second part of the equation is the fan speeds of the radiator.
Are they running at full speed?

I see your BIOS is extremely old, and although something may not be mentioned doesn't mean it hasn't been fixed.
Too much scare mongering here about bios updating. If you are capable of updating the bios, I would.
Also don't forget, the bios will protect you from the 200 bugs built into the Intel Architecture.

MERGED QUESTION
Question from adshidi : "My 6700k CPU is touching 70°C when idle"

I ve been monitoring heat with speccy, HW monitor, AI suit - all of them indicate upward of 65°C ar idle. Sometimes touching 85°C and when the temp rises the fans speed up notoriously ane the CPU works up above 40% in Task Manager. Though my computer is 21 months old I had to replace my PSU and motherboard a month ago as for some reason the motherboard was failing. It was booting up but fans and monitor was not responding. I sent both the PSU & MB to the respective companies & they replaced them. I never used to monitor temp. Now I do it. And it is giving me worries. The funny part is, whenever I restart my computer the the heat comes down to around 35°C. I have CM seidon 120v AIO cooler installed on the CPU, and the thermal paste is also reapplied during the installation of the new MB. The cooler apparently is working fine as the blue light on the pump is visible and the pipes are are also vibrating , also in AI suite water pump is showing 2400 rpm constant speed. Whenever I open the computer by pressing the button, the QR code on my asus MB is displaying 40, but after restarting the code turns into AO. Another thing is that the new MB that I have received has BIOS 1701 on it while asus site shows many updates after 1701. The latest one being 3801. I want to know from you guys, will updating BIOS solve the heating issue, or should I also send the cooler for a checking at the company? I keep hearing horror stories regarding BIOS update, so I have to muster up a lot of courage to do so.
Though I live in a hot and humid region and my room is not air-conditioned either, 65 to 70 degree at idle is still a lot of temp. I am not a gamer and I don't need to over clock my cpu. I need to edit a lots of videos and do vfx works. If this computer gives in I won't be able to buy another one readily. So I am seeking your help. There are many wise and knowledgeable persons in this forum. Hope, someone will show me the right way.

AIO cooler - Cooler Master Seidon 120 V. (also have a LG DVD writer installed which is also not working properly even after one replacement)

Yeah that's very worrying. Are you sure the thermal paste is applied properly? Or maybe the Heat Sink isn't placed properly. Have you tried a different monitoring software like MSI Afterburner or CPU-Z?

Touch the AIO radiator to check how hot it is. If it isn't hot enough, it means theres a gap in the coolant circulation and the liquid coolant inside the AIO is not transferring heat (has stagnated).

Do you have any air cooler lying around???

I didn't replaced the MB myself as I have never done it before. Instead I have hired a guy who replaced it while I was present. As far as I remembered, the paste was applied properly. I am wondering why it is behaving right only after restarting? As far as radiator is concerned it is remaining cool.

I think the problem might be in the thermal paste application. The radiator shouldn't be cool when the chip is at 70'C.

The mobo code 40 is indicating that your pc is returning from sleep/Hibernate state (Default shutdown in Win10). The error code isn't the problem.

Ok can you go into the BIOS and see if you CPU is overclocked?

I hardly understand this BIOS lingo as I don't frequent this space. As per your suggestions I went to bios and saw that cpu core/cache voltage is pegged at 1.264v, DRAM at 1.200v, cpu VCCIO at 0.976v, CPU system agent at 1.080v, PCH core at 1.008v CPU standby at 0.975v. There are many other options all of which are resting at auto. Does that suffice?

The problem persists. Upward of 60°C at starting the computer and continuing to be so unless I restart. After restarting, the temp is normal at 35°C. Is the future of the mechine at stake? Someone should come up with a solution.

The pump is either not plugged in, or has failed...(happens often enough with AIOs, more often than most want to admit)

The radiator being cool tells you nothing warm is flowing thru it..

The problem persists. Upward of 60°C at starting the computer and continuing to be so unless I restart. After restarting, the temp is normal at 35°C. Is the future of the mechine at stake? Someone should come up with a solution.

Do this:

Option 1:
Go into the BIOS setting -> Load default settings (F5) -> Save and restart
It should work if you CPU was overclocked too much and cool your CPU down:
Option 2:
Call the service guy to check the AIO and get a good air cooler.

That's it, I don't see anything else to be the problem. It might be the BIOS settings that could cause this but the chances are pretty lean.

I will try it for sure and thank you very much to take your precious time out just to help me. I will post whatever may come of it.

geofelt , my cpu fan is at1000rpm. One chassis fan at 1100 rpm, another chassis fan was spinning and stopping few days back, but now spinning at 500rpm

OK, I searched the web for normal operating temps and max temps for your Intel 6700K CPU. This page

http://www.buildcomputers.net/cpu-temperature.html

says it idles up to 35C, "normal" is 53 to 70C, and Intel's recommended max is 72C. That last is conservative - the internal Intel protection systems will not throttle the CPU until significantly higher than that.

In many forum posts people suggest 60C is just fine, 70C should be about the max for heavy use, and over 80C is a bit too high. Many have seen close to 100C during heavy gaming but considered that too high and worked on improvements to cooling. One thread poster told a story of changing his cooling system because of temp worries and improving it until he was very satisfied that it ran at 60C even when working hard.

OP, your system can run at 35C just after start-up with no real load on it - that is normal. It gets up to 60C when gaming but rarely exceeds that. During that performance the rad fan speeds are not maxed out, indicating that the mobo automatic CPU temperature control system believes that is a perfectly acceptable operating temperature AND that there is reserve cooling capacity if the temperature starts to rise further.

It appears your CPU is operating at normal and acceptable temperatures. Do not expect it to stay at the 35C value you see only when it is at minimal workload.

Paperdoc, know my gratitude for working hard for me. Yesterday I was editing on premier pro and the temp touched 98°C. My heart sank. I immediately restarted the pc and opened premier pro again. Initially it touched 70°C, but then gradually it came down to below 40°C, and I heaved a sigh of relief. I am baffled by it. If there was any cooler issue it wouldn't have shown this duality. Please tell me if I should update the BIOS. Mine is 1701, and the latest on asus site shows 3801. Many people advised me not to tinker with bios without proper knowledge, even asus manual states that the bios update could turn out to be dangerous. I need guidance. I am also not sure if I should send the cooler for a RMA. But there is something wrong in the system. Your help will go a long way. Thank you once again. May you have a prosperous life.

What you describe recently (and maybe earlier) looks like intermittent failure of the cooling system. This could be a result of loose connections, so check those for both the pump unit and the rad fans. For each, unplug its connector to the mobo header (plus any connection to Splitters or such), then re-connect. Do this several times, in case there is oxidation on the contacts that will be scraped off. Check to be sure they are re-connected securely, and that nothing else was disturbed while you were working.

Another thing that can cause this is loss of the fluid in the AIO cooler water loop. If some of it is lost you can get large air bubbles trapped in the loop. Especially if there is air in the pump itself, it may not actually pump anything around the loop even though it is running. The pump in this state is said to be "air-bound". Often shutting the system down and re-starting can move the bubble in the pump out so that it can work again when re-started. Perhaps ask Tech Support at Cooler Master if they can recommend the proper way to check for lost loop fluid and re-fill it if necessary.

Hi, paperdoc, thanks mate, this sounds very convincing to me. Tomorrow earliest I shall contact the cooler master service centre, and I shall post the updates.
