FAN are very loud on ODS

Jump to solution

Hello,

we have a new type of computer in our company and at every time a ODS is starting the fan is starting to rotate with high speed and is then very loud. When this behaviour occur the task mcshield is on 100% CPU Usage. All symptoms stopping when the ODS is ended. It is equal if you starting the ODS manually or by client-task from ePO server. It is the only type of computer that is affected.

Computer: DELL Optiplex AIO 7460 8GB

OS : Win10 1809 LTSB

ePO: 5.9.1

ENS: 10.6.1

HF: 190514 & 190212

MA: 10.6.0.887 & 10.6.1.157

Have anyone the same problem or know a solution for this?

Thank you in advanced for your help

Olsen

Best Regards
Olsen

Sorry, for my late reaction and that i have bothered you with this issue. Also thank you for your your helpful hint.

We have make some tests and have found out that the computers seems to have a problem with the cooling of the cpu. After a repair of one device, on which the fan and the cooler were changed, the noise of the fan are normal while the Scan-Job of McAfee.

Thank you very much for you support

kindly regards

@Olsen 

High CPU during ODS is expected behavior and is by design in order to get scans completed as quickly as possible and lessen the window at which the system is at higher duress due to full system scanning alongside the continuous On-Access Scanning. Windows process prioritization will provide the scanner with all of the available resources for this reason, until a process with higher priority requests use where it will temporarily hand it off to the requesting process before handing it back to the scanner. For this reason, we advise that your ODS be scheduled at a non-peak business hour, or on weekends, in order to limit the impact to the end user.

The first configuration change that can assist in making significant changes to scan duration and performance is disabling scanning of archives during ODS. This is considered to be a very minor to non-existent security risk because all files inside an archive are scanned when the archive is opened or extracted, making scanning these files redundant, because OAS will scan the archive if it is accessed or opened at any time and scanning them during an ODS can take some time. This extended time to scan the large archive files prevents Microsoft's priority allocation for resources from handing the processing power to other processes that request it until the entire archive is scanned or the default 45 second timeout is reached. If there is a large number of archives on a system, this scenario is more frequent and can create significant impact to performance and scan duration.

The second change is to change system utilization from normal to low in order to set us at the lowest priority for resource allocation. Please keep in mind that this will not eliminate increased CPU consumption by ODS, but can increase the frequency and speed at which resources are handed off to other processes via priority leveling of the OS.

Third, you can look to implement the option of "scan only when idle" in order to only allow the ODS to run when the OS has signified the system is in an idle state and will allow the ODS to run. If the system comes out of idle, the scan will pause until next idle.

 

We recommend that you look towards these config changes to assist in lessening the impact of the ODS. However, as described, high CPU during ODS is expected by design, and there is not much that can be done to make a dramatic difference in scanning. Please review the following article that go further in depth in regards to these concepts: KB55145

You can also review the best practices documentation for optimum ODS configuration: KB74059

 

Please be advised as well, with the future release of ENS 10.7, there will also be the release of a feature which will allow for enhanced control and administrator limits against CPU consumption by ENS. It sounds like this could be a feature that you would be very interested in, and I recommend that you look to future release information regarding this product release 🙂

@jess_arman 

thank you for your quick and detailed answer. All hints do you have given to me in your answer i already have done. I know that that the process need a high cpu consumption to ending the task as quick as possible, but only this type of computer have this problem. I thought i get a hint from anyone in this forum if this may be have  an cause in any Microsoft Patch or equal.

I will install this computer with windows 7 yet and test if it has the same problem or not.

An defect of the device can be excluded, because more than one device is affected.

I will report what is the result of this test.

On the mentioned new features of ENS 10.7 I am very curious. Maybe they are the solution to my problem.

Greetings

@Olsen It is possible that you do not have sufficient hardware requirements to be able to handle load of everything the system is being asked to do. With the fact that your fans are spinning high, it sounds like your system is just struggling to keep up on all counts. Poor performance and hardware reaction like this is not always indication of a software issue, but a hardware limitation and lack of physical resources.

You mention you'll move the system to Windows 7...what OS version are you currently on and what version of McAfee software are you running?

I don't think that the hardware requirements are not fulfilled. It is a up-to-date system by DELL.

All data do you want to know are described in my first post.

Hi Olsen,

 

I did a little bit of research on this model and it seems to have a loud fan by default.

For example:

https://www.pcmag.com/review/364759/dell-optiplex-7460-all-in-one

"CONS Loud cooling fan frequently engages. "

 

I hope this helps!
