PowerShell Scripting output issue

Hello All ,

I have created below Script, the script is working fine and display the correct output with NumberofCores on the Screen. like NumberofCores             : {12, 12}

But when I export it into CSV, under the NumberofCores colum, it display "System.Object[] "

Here is my script"
$servers = Get-Content C:\temp\servers.txt
$Output = @()
foreach ($server in $servers) {

if(test-path \\$server\C$) 
{
$os = Get-WmiObject -Class win32_operatingsystem -ComputerName $server 
$cpu = get-wmiobject Win32_ComputerSystem -ComputerName $server 
$cores = get-wmiobject Win32_Processor -ComputerName $server
$data = @{
    "ServerName" = $os.PSComputerName
    "Model" = $cpu.model
    "OS" = $os.caption
    "OSArchitecture"  = $os.OSArchitecture
    "NumberOfProcessors" = $cpu.NumberOfProcessors
    "NumberofCores" = $cores.NumberOfCores
    "NumberOfLogicalProcessors" = $cpu.NumberOfLogicalProcessors
        
}
$output= New-Object -TypeName psobject -Property $data
$output | Export-Csv C:\temp\Info.CSV -Append -NoTypeInformation

}
else
{
write-output "$server" | out-file c:\temp\errors.txt
}
}
