The Dr. Thermal TI-V77 heatsink looks a lot like a Thermoengine, and quite similar to Arkua heatsinks. This heatsink is pretty low profile and would work well for rack mount servers. The Dr. Thermal has the dimensions of 73.8×73.8x46mm and weighs 276.5g
The Dr. Thermal comes in a lime green box and is packed quite well. This heatsink comes with a thermal pad and also comes with thermal compound so you can choose.
As you can see from this shot Dr. Thermal is pretty low profile. Dr. Thermal uses a unique clip design, the clip doesn’t move very much and it uses a retaining arm to tighten it down. What you do is while the retention arm is up you clip both clips to the socket which is pretty easy to do and then put the arm down which tightens it into place.
Dr. Thermal comes with a YS Tech fan, model # FD1270157B-1F here are the some of the specs of this particular fan.
Here is a shot of the top of the heatsink with the fan removed, as you can see it is not hollow it is solid all the way through with the copper core as well. The base of the heatsink as you can see has the thermal pad on it which I will remove for testing.
I installed Dr. Thermal to the test bed, because the copper core of the heatsink is centered it does not align with the core of the CPU as you can see from the picture below. What I did to resolve this problem is flip the heatsink around. After I did this the core was more centered onto the copper slug, not perfect but better. Like always I will be using Artic Silver 3 for testing, I will also be using an external Compunurse thermal probe for the temperature readings. I took a picture of how exactly the probe is installed on the CPU.
I let the computer boot up and idle for about 20 minutes, and took the readings from the probe. I then used Prime95 to torture test the CPU and bring it to load. The test like I mentioned before was done with the heatsink flipped so that is was better centered onto the core. This heatsink does an alright job cooling the CPU however I would not suggest you use it for overclocking because the load temps are almost at 50 degrees Celsius.
This heatsink performs all right, because of the design flaw the results are higher than they should be. This is a good heatsink because it’s low profile and is not very loud. The clip design is good and easy to use, not requiring tools. I would not suggest this heatsink to you if you are looking for one to use while overclocking. If you are looking for a non-overclocking heatsink for a low profile system this will serve you well.
Overall I would give this heatsink a 6/10. I would like to thank HighSpeed PC
