Hp Elitebook 8770w additional fan for cooling?

Hi there,

Has anyone ever tries to successfully add another fan Man in there HP Elitebook?

If so, please can you advise the best of doing this safely.

Any help is much appreciated.

Many thanks

Nope. You can try better paste and you can grinding the radiator.

 

Thermal Grizzly Kryonaut brought the temps on my 8770W to 66-69C max for the GPU and 84-88C max for the CPU when both used together under heavy 3D load in Far Cry New Dawn.

 

I am interested in this too.
I have just now upgraded my k3000m to 680m, but temp goes much over 80c degrees. Even when manually setting fan to run 100%.

I was thinking about cd-rom slot cooler, or just adding more heatpipes. Dell had 3 gpu heatpipes.

There are some kind of vaccum coolers which should be attached outside of case, but i doubt about their efficiency. Interesting to see other peoples upgrades on this notebook

 

Interesting job. Thanks.
Do you use manual fan control or everything works fine by itself(I was thinking about connecting gpu with cpu with additional heatpipe to get automatic fan working better, because ir kicks in only when cpu get highemp) ? What rpm has your new fan? What cfm? I saw some of them can get 30cfm on ebay, don't know if it can be true

I was thinking about connecting gpu with cpu with additional heatpipe to get automatic fan working better.
Why you connected new heatpipes on top of old ones? Why not side by side? I see You have flattened old ones, how much? Can you share what termoglue you have used?

 

Hi, there is no point to glue the new heatpipes next to the old ones, as the nickel is poorer thermoconductor. The best result is on top of the old ones, where the copper plate can directly transfer the heat to the all four heatsinks.
It was used this one for gluing them together:



My current fan is 13+ cfm, 3840rpm from zBook 17 G2 and I am waiting a new one from HP Pavilion all in one pc 24-xa. It has 11 more blades (30 vs 19) and it is rated as 1.3A.
There is no way 5V can reach 30cfm.
Most powerful of them are ~13-14cfm

 

How do you know if fan is right height and diameter?

Why not choosing for example this

Or this
https://a.aliexpress.com/LiUhQNBCJ

Or this( claimed 30cfm)

Can you share 8770w fan diameter and height from the base? Are you cutti g out base with dremel? As far as i could find, your fan has different (wide) metal base.

No way the last one to be 30cfm except for being 12V which is not supported by our mobos.
The other two are taller (15mm vs 12mm) and won‘t fit in our laptop without Dremel work.
The one I choose is the best one fitting inside without any need of heavy case modifications.

 

I spotted that hp 24xa fan turns different direction? Or i am wrong? Can you write part number if i found wrong one? 47N76FATP10 this one? https://rover.ebay.com/rover/0/0/0?mpre=https://www.ebay.com/ulk/itm/223766934028

 

It is the same direction:



The blades turn right at the end, they are just different shape, this makes them more efficient.

 

Well i feel stupid a little ..


This is 8770w genuine fan. The one , you are awaiting, looks mirrored...

Maybe it just mounts upside down.

But never mind. Maybe i misunderstand something

 

See? Same direction:

 

well... please keep updated when will change fan. its interesting how cooling will improve with this fan. thanks

I have disassembled my laptop yesterday to verify fan(installed curently in my laptop) dimmensions, and made a printable drawing(for modifying base plate), in case anybody need it in future.

 

I have just installed new fan. 5v 0.58a. 17 leaves "sunon". Genuine was 0.5a.

Interesting fact, that top speed is just 80%.
Hardware monitor show Cpu fan max speed 3200rpm and fan2(wherever it is 3800rpm max). Temperature so far so good 80 max. No oc on 680m for now

 

Yesterday I did install the fan from HP Pavilion 24 All in One PC, I modded it to fit the heatsink:



The fan is rated 5V, 1.3A and spins at 4100rpm.
The noise is waaay too disturbing compared with the fan from zBook 17 G1/2 (which I find btw the quietest among all I’ve tried).
The results are very unexpected:
The CPU is 5-7C hotter (78 vs 72) the GPU is 2-3C cooler (74 vs 76). In any way it was complete waste of time and effort and I went back to the fan of zbook which I find the best for 8770W. Quiet and effective.

 

Cpu gets better cooling with genuine fan and this one give better cooling to gpu because it turns other side as i mentioned before. You could try to install it upside down to get correct airflow direction to see if it can get anything better. But it can be that you need to get bigger vents from downside of notebook... Maybe its peak air flow with current vents.

I am still thinking about additional fan in dvdrom slot for gpu with additional fan and radiator via 2 8x3 heatpipes... Just need to find additional radiator that fits into dvdrom slot.

 

Nice mod! I hope you are going to retest it upside down.

There are server heatsinks that might fit the bill.

 

There are a couple ebay/aliexpress sellers that sell heatsink fin stacks, with a dozen or more formats to choose from, dvd slots from that era where made for 12mm thick drives, measure the lenght available, take some for the pipe bend radius and order some 12 by 20/30mm(fin "depth") by the lenght measured up and order a pair.
Order a bit of chipquick bismuth 132ºC solder to solder it all up without damaging the heapipes and see how it goes.

 

Have any link to it?

Too laud....
Not worth it. It is like turbine, can’t stand it for more than 5 min.
The one from zbook 17 g1/2 is just perfect.
Amazingly comfortable as loudness and still very effective at the same time. Definitely a keeper!

 

Fair enough. Great fan indeed.

 

i did test with my laptop... i believe there may be easy mod to cooldown laptop by 4-5 degrees.i got this result by removing keyboard. need to cutout grill from the back(maybe it would help)...
it would be interesting to know results from others....

 

By saying grill you mean the dust filter from underside?
I did remove it, gained 2C difference

 

No. Not dust filter. I have removed it too when i was swaping gpu. I mean plastic grill. I believe There could be at least 20% more air flow on same pressure if there were no grill at all.

Well. Thats just the thought

 

Where exactly is this plastic grill?
Can you send me a photo?
I am asking because on those machines there is no plastic at all except screen frame

 

This grill. From downside. Where dust filter were

 

Plastic, you say ))
This is magnesium and will take a lot of effort to get it removed,)
I personals wouldn't...it won't make any significant difference- 1-2C at most.

 

Well... Didnt noted it could be metal parts... Just looked at color and that it is moulded part, not bended like sheet metal


But you see how many i got from removing keyboard... So it means that grill is blocking airflow

 

Found my old laptop. Decided to check if heatsink may fit my current mod. Well. Can't expect any better fit.
Going to mod current heatsink so i could fit lowered heatpipe on side of old ones. so i dont need to cut plastic, i do not plan solder new heatpipe. Will make couple holes in heatsink and will screw new heatpipe using additional copper plate(in case i will decide to get dvd back...and need to cut holes from downside to get free air in.

P. S. I did put this heatpipe now without any modding. Plastic above dvd pushed heatpipe down to heatsing . I put thermopad between them. New heatpipe is heating perfectly without soldering.

 

Hi all.
So. I have installed additional fan(i will upload photos later) . Temperature of gpu went down by 20 degrees. 70c when running 3dmark and up to 80 when gaming(after 40minutes).

Now i am searching for pwm temperature controller. There are plenty of them with 12v voltage, and cost few euros, but no 5v

I want independent fan control, but do not want any manual switches. Its a bit loud cooling now even if gpu is under 40, but with high cpu usage(working with cam/ cad)

Maybe somebody has seen anything like this?

 

Which gpu do you have?

 

Dell 680m 2gb. Got it for 50eur

 

May be 680m is hot gpu natively , because without any mods my cooling was holding Quadro M5000M (OCed 1200core/5300mem) max 70C after hour of heavy gaming, after adding two more heatpipes, my current setup is holding GTX 1070 at 80C max after hour of Borderlands 3 (99% GPU load).

 

I have never checked temperatures when i was on k3000m...

What is your cpu temp? Mine is going up to 95 on heavy gaming (world of tanks, this game makes my laptop hotter than any other game)

Now i am curious about driver crash when trying to play after oc. It works good without oc. Also benchmarks works perfect with or without oc

 

My 3840QM is max 73C on XTU stress test and 82C max together with GPU on most heavy 3D games.
I am on LM though...
Your mod looks great btw
What is your CPU?

 

well. i got 102 just right now on cpu ... need to check maybe heatpipe is empty or something....

 

Which i7 do you have there?
102C is insane, you will kill it.

 

3740qm. I dont get such temp on gaming.max 90-92. This was on stress test you have mentioned...


Well. Now i think something is really wrong with cooling at my side

 

there is definitely something wrong with your cpu cooling...
just check if the screws are secured properly or the vents on the heatsink are clean.
If yes, the worst scenario would be bend/interrupted heatpipe...

 

what is LM?
I wish i could findout what is wrong... screws looks fine. thermal paste mx4, spread perfectly.
Need to buy multimeter with thermal probe to test heatpipes... they feels heated equally now when touching...

 

LM= Liquid Metal

 

I know this is an old thread but mirage_bg where did you get the heatpipes you used for your cooling mod??

 

You can find any size and thickness on AliExpress.

 

Awesome thank you!
