Latitude E7450 heatsink not covering cooling surfaces

Welcome to the Dell Community  @JS92 

That is not the heat-sink for that CPU.

You need this one:

Dell part number: H0WK4

Please use your "Service Tag" to look up your system configuration.

Please post back with the "Heat-Sink" part number and the "CPU" model number???

@JS92 

Any update???

Thank for your response. The number is 7Q11F72. I did not find any of the information that you asked for on the link that you sent. I looked in the configuration and spare parts sections. Furthermore there is another thread here on Dell in which someone claims that it should be that way, for some reason only one chip should be covered. Here: https://www.dell.com/community/Laptops-General-Read-Only/E7450-heat-sink/td-p/5054994

I am starting to think that it should actually be this way, although it is very strange and looks wrong. Also I read these models are known for running hot so maybe it is designed that way. 

Best regards

Thanks, 

So I do have the correct heatsink? 

Thanks

Hi @JS92 the information that you have linked to is correct and the explanation of why is explained in the post. The heatsink was redesigned so that the north bridge would not be making contact with the heatsink. Whereas the part in your system is correct, it's the original part that shipped with the system. The part number that you require for the revised heatsink is TW22Y.

@Dell-Alan D 

Thank you for explaining the initial design flaw and the followup redesign of the heat sink.

Hi all!

Dell-Alan D, how would one know there was a part redesign that would benefit system health and customer satisfaction? I mean for any Dell product...

Thanks

My warehouse tech's process around 100+ of these units a month.

Is there a quick way to tell if they have the poorly designed heat-sink without removing it to check???

And is there any exchange policy for the same???

@U2CAMEB4ME I cant think of an easy way to check other than checking the service tag on the support tag and checking the heatsink part number on the components list.

A warranty exchange would only be made if the system is exhibiting thermal issues although with the age of the xx50 systems I would expect the majority of them would be out of warranty by now unless they were purchased with a 5 year warranty.

Hi, i am an e7440 owner. 3 Days ago i renewed my thermal paste but temperatures were still high so i was researching what can be done about it. Then i saw this topic 3 hours ago and i realized that my model had the heatsink that covers both chips. 

 Started to look for on the internet if theres a new design heatsink for my laptop but i cant find any heatsink model that leaves one chip open for the e7440. So i decided to repaste my cpu and dont put any paste on the north bridge chip thus it doesnt have as much contact with the heatsink as before. Result is; 6-7 degree lower average temperature on the cpu.

 So my question is that if dell decided to make a new heatsink design on the 7540 model but didnt care about 7440 model or i cant find the latest updated heatsink on the internet for my laptop?

Thanks

 Since its obvious that the part that covers both chips is a flawed design i am curious if Dell should send me the revised-new heatsink without any charge? I think it should be so.

@Dell-Alan D

@Efeatmaca the heatsinks are the same for the E7440 and the E7450. Depending on whether you have integrated or discrete graphics determines which heatsink you require.

Integrated - TW22Y
Discrete - CCN54

Those are the parts numbers you require for the revised heatsink.

Alan

Hi @Efeatmaca the system was introduced 6 years ago. As the warranty has long since expired, I am afraid I cant replace the heatsink on the system free of charge.

Alan

 I am a second hand e7440 owner which i bought 10 days ago. Since this flaw is a hidden defect the guy i bought this had no chance of knowing it without a deep investigation. 

 Thats why i think Dell should help me on a 35$ part
