Overheating Precision 7510

[Reshen]

So in anticipation of the arrival of my new 7670, I wanted to get my current 7510 in tip top shape. I'll keep it as a secondary because it's still very capable.

 

Thing is the system tells me a fan has failed. I wanted to order the replacement part but Dell (in South Africa) is not supporting this unit anymore. I can still run the unit though after bypassing the warning.

 

I'll only start fiddling when I have the

new unit is configured. But I did some investigation and it seems the fans are turning. The machine has had a new motherboard under warranty, so things were moved. So I'm wondering if I should first try to reseat and paste the cooler before finding a new part on eBay or wherever?

 

Any other ideas on what to check before I open it up?

I got a fan malfunction on my (similar) 7520 when it was new. Dell replaced it under warranty. They replaced the whole fan assembly unit, cooler and heatpipes included.

 

This is how the malfunctioning fan sounded.

Mine makes that periodic fan noise at start up. Right now after being on the whole day, on the dock, the fans are steady but at 60%. No load on the system and the CPU temps are 50 deg celsius.

If there is no load on the system, the fans should cycle between the lowest level (≈2400 RPM or less) and off (0 RPM).

 

Assuming the fans are plugged in properly, if the system is complaining about a fan failure and it is behaving strangely with regards to the fans... it's gotta be either the motherboard or the fan.  I don't think you can (easily) separate the fans from the heatsink assembly in this one.  Even if you could, it looks like the price for buying a set of fans or a whole heatsink (with fans) is about the same.  You can purchase a heatsink assembly on eBay for $25ish (USD) — I would assume that some sellers offer worldwide shipping.  Of course, removing the heatsink will also require applying new thermal paste when installing a new one.

 

There are different versions of the heatsink assembly (depending on the GPU, I think).  If you are going to pick up a new one, put in your service code at dell.com/support and look at the parts list for your system to see which one you have.

Thanks @Aaron44126

 

I've got the exact part number i.e., the one for NVidia GPUs. 

 

I'll give the repair a go as soon as I have my new unit.
